Uniaxial anisotropy ferromagnetic particles

A single domain ferromagnetic particle with uniaxial anisotropy but excluding the effects of an external field... [Pg.275]

Easy axes of alignment of the magnetization, or an anisotropy, often exist within a single domain ferromagnetic particle. The simplest form of anisotropy is uniaxial anisotropy in which the magnetization favors either of two opposite directions. This may be represented in the framework of our analysis by means of an anisotropy potential of the form... [Pg.286]

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]

Using this method it is possible to calculate the longest relaxation time of M for a single domain ferromagnetic particle with large uniaxial anisotropy. It is also possible to calculate the longest relaxation time when the particle is in the presence of an external magnetic field applied... [Pg.319]

The relaxation time T (o-, ) for the magnetization of a single domain ferromagnetic particle with uniaxial anisotropy in the presence of an external field from T = Mp and Eq. (3.129) is... [Pg.324]
