VI. THE CALCULATION OF RELAXATION TIMES FOR A SINGLE-DOMAIN FERROMAGNETIC PARTICLE FROM GILBERT S EQUATION... [Pg.354]

In this section we summarize the approach used by previous authors [8, 16-19] to find expressions for the relaxation times of single domain ferromagnetic and ferrofluid particles. We begin with the Fokker-Planck equation obtained from Gilbert s equation, in spherical polar coordinates, augmented by a random field term, that is, with Brown s equation. We then expand the probability density of orientations of M, that is. [Pg.301]
