Neel relaxation single-domain ferromagnetic particles

ON THE THEORY OF DEBYE AND NEEL RELAXATION OF SINGLE DOMAIN FERROMAGNETIC PARTICLES... [Pg.263]

A single domain ferromagnetic particle suspended in a fluid is subject to two orientational variational mechanisms. The first is that discussed already and takes place inside the particle, it is the solid state mechanism known as Neel [25] relaxation. The second is due to the rotation of the... [Pg.283]

In this section we consider the dependence of the relaxation time on the internal anisotropy of a single domain ferromagnetic particle. Thus it is applicable only to Neel relaxation. We consider the simplest form of anisotropy, namely uniaxial anisotropy described by the potential... [Pg.313]

These equations govern the Neel relaxation of a single domain ferromagnetic particle. They bear a resemblance to equations (5.26)-(5.28) for the Debye relaxation of ferrofluid particles (with the Neel mechanism blocked) subjected to a weak AC field superimposed on a strong DC magnetic field H. They differ from the ferrofluid equations, however, insofar as they contain processional terms g and... [Pg.359]
