The NATO Advanced Research Workshop Bianisotropics 2002 was held in th Marrakesh, Morocco, during 8-11 May 2002. This was the 9 International Conference on Electromagnetics of Complex Media, belonging to a series of meetings where the focus is on electromagnetics of chiral, bianisotropic, and other materials that may respond to electric and magnetic field excitations in special manner. The first of these meetings was held in Espoo, Finland (1993), and the following venues were Gomel, Belarus (1993), Perigueux, France (1994), State College, Pennsylvania, USA (1995), the rivers and channels between St. Petersburg and Moscow in Russia (1996), Glasgow, Scotland (1997), Brunswick, Germany (1998), and Lisbon, Portugal (2000). The present book contains full articles of several of the presentations that were given in the Marrakesh conference. In Bianisotropics 2002, 8 re view lectures, 14 invited lectures and 68 contributed talks and posters were presented. Of these presentations, after a double review process, 28 contributions have achieved their final form on the pages to follow. From the contributions ofthe meeting, also another publication is being planned: a Special Issue of the journal Electromagnetics will be devoted to complex materials. Guest editors for this issue are Keith W. Whites and Said Zouhdi. The chairmen of Bianisotropics 2002conference were Said Zouhdi (Pierre et Marie Curie University - Paris) and Mohamed Arsalane (Cadi Ayyad University - Marrakesh), who were assisted by Scientists from Moroccan Universities and the International Bianisotropics Conference Committee.

The 1986 Advanced Study Institute on "The Physics of the two-Dimen sional Electron Gas" took place at the Conference Centre liTer Helme", close to Oostende (Belgium), from June 2 till 16, 1986. We were motivated to organize this Advanced Study Institute in view of the recent experimental and theoretical progress in the study of the two-dimensional electron gas. An additional motivation was our own theore tical interest in cyclotron resonance in two-dimensional electron systems at our institute. It is my pleasure to thank several instances and people who made this Advanced Study Institute possible. First of all, the sponsor of the Advanced Study Institute, the NATO Scientific Committee. Furthermore, the co sponsors: Agfa Gevaert, Bell Telephone Mfg. Co. N.V., Burroughs Belgium. Control Data. Digital Equipment Corporation, Esso Belgium. European Research Office (USA). Kredietbank. National Science Foundation (USA). Special thanks are due to the members of the Program Committee and the members of the Organizing Committee. I would also like to thank Mrs. H. Evans for typing assistance.

Launches of several major magnetospheric research satellites (i.e., Polar, Wind, and Interball) set the scene for extensive multi-platform investigations of the Earth's plasma environment in the era of the International Solar-Terrestrial Physics Program. Exciting new results from this Program and the ongoing innovative advances to scientific instrumentation and spacecraft technology are vitally important for the international space community in preparing for future plans in the upcoming new millenium. This volume is a product of the COSPAR Colloquium held in Beijing on April 15-19, 1996 aimed to consolidate these achievements. It contains state-of-the-art articles in the four areas of modern magnetospheric techniques, namely, (1) active experiment in space, (2) innovative measurement technique, (3) multi-point observation, and (4) numerical simulation and theoretical analysis. Researchers in the space community, both novices and experts, are expected to benefit from this collection of articles.

Magnetic skyrmions have attracted substantial interest due to their potential for use in spintronics devices and next-generation information storage, and due to the novel phenomena that result from the topological winding of skyrmions. In this dissertation we theoretically study the properties of magnetic skyrmions in chiral magnets. We focus on two key parameters that must be optimized to achieve maximum device performance: skyrmion size, and skyrmion stability. Skyrmions are stabilized in materials where inversion symmetry is broken. We show that the skyrmion crystal phase is more stable in systems with broken mirror inversion symmetry compared with systems where only bulk inversion symmetry is broken. To understand this effect we study a system where both mirror and bulk inversion symmetry are broken. We show that broken bulk inversion symmetry tends to stabilize a conical phase, and this phase becomes progressively less stable when broken mirror inversion symmetry is introduced. The phase diagram reveals a large region of skyrmion crystal stability, as well as a stable elliptic cone phase, and a square skyrmion crystal phase. In addition to crystal structures with broken inversion symmetry, the presence of an interface in magnetic films introduces a source of broken mirror symmetry. We show that this added source of symmetry breaking enhances the stability of the skyrmion crystal phase. Films surfaces and interfaces also stabilize a novel phase of matter called a chiral bobber crystal. This phase can be uniquely identified by the presence of a two-dimensional lattice of singular points in the magnetization field called Bloch points. We present experimental evidence for the observation of a chiral bobber crystal using magnetization data. Skyrmions can also be found outside the skyrmion crystal phase as metastable, particle-like excitations with a finite lifetime. We show that the lifetime and size of skyrmions have a strong interdependence. Putting limits on the lifetime of a skyrmion also restricts the range of skyrmion sizes. For a given lifetime, the smallest skyrmion size is determined by competition between the exchange interaction and the Dzyaloshinskii-Moriya interaction. We also show that the lifetime of a skyrmion depends essentially on two parameters: the energy of a skyrmion, and the energy of a Bloch point. In two-dimensional systems (magnetic films and interfaces), the Bloch point forms in space-time; in three-dimensional systems, the Bloch point forms totally in space and has the structure of a chiral bobber. Finally, we show that entropic corrections to the lifetime are typically small, except near a special point in the phase diagram where skyrmion size diverges, and soft-modes contribute to a divergence in the entropy of a skyrmion.
