Aside from its practical aspects (such as magnetic recording), it addresses readers interested in the basic physics of nonlinear phenomena. - ;Electrons in solids behave like microscopic bar magnets, and in certain solids these align to produce macroscopic magnetizations. This book deals with the dynamics of this magnetization field. It addresses questions of microscopic mechanism only to the extent that residual interactions of the mag 410 0$aInternational series of monographs on physics ;$vv. 133. 606 $aMagnetization 606 $aEquations of motion 606 $aMagnetic recorders and recording 608 $aElectronic books. 615 0$aMagnetization. 615 0$aEquations of motion. 615 0$aMagnetic recorders and recording. 676 $a538/.3 700 $aSuhl$b Harry$050044 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910465814603321 996 $aRelaxation processes in micromagnetics$9716555 997 $aUNINA
