Applications of micromagnetics

摘要: Abstract The main idea in the original development of theory micromagnetics was to avoid crude approximations and arbitrary assumptions constraints used domain theory. It hoped that a could be built which would describe rigorously all magnetization processes, from nucleation wall surrounding reversed domain, through motion this crystal, its final disappearance saturated sample, including high-frequency phenomena like ferromagnetic resonance. In principle goal can achieved, at least for ideal crystals, by solving certain set non-linear partial differential equations. solution is definitely not easy, but it done relatively simple cases with modern computers. Choosing, say, spherical single crystal an appropriate material, should lead computations are very lengthly, prohibitively so. reason has never been known advance such ...
