This book covers the main aspects of dynamic phenomena in confined magnetic structures so that researchers can find a comprehensive compilation of the current status in the field. Introductory chapters help newcomers to understand the basic concepts, and the more advanced chapters give the current state of the art for most spin dynamic issues in the milliseconds to femtoseconds range. Emphasis is placed on both the discussion of the experimental techniques and on the theoretical work. The comprehensive presentation of these developments makes this volume very timely and valuable for every researcher working in the field of magnetism.
It describes the new experimental techniques which have advanced this field very rapidly. Among the techniques covered, particular attention is given to those involving high temporal and spatial resolutions, down to the femtosecond and submicrometer regime, as well as to techniques involving magnetic field pulses with very short rise times and durations, and new detection schemes.
