Abstract

A theory of magnetic anisotropy both of induced and thermoremanent magnetizations due to non-interacting single-domain and multidomain magnetite grains of arbitrary distribution, is developed. The model samples consist of uniaxial, ellipsoidal grains occupying the cube corner sites in a cubic lattice of which the cell size is one of the input parameters. The magnetostatic interactions is assumed to take place: 1) at room temperature in induced magnetization models, and 2) at the blocking temperature in thermoremanent magnetization models. Each model is treated with and without taking into account this interaction. Further, the six directional remanences are used to compute the anisotropy ellipsoid of the respective remanence and its parameters including the magnitudes of the principal axes, their directions with respect to the sample, degree of anisotropy, etc. and finally the angle and direction of the maximum refraction. -from English summary
