This expression accounts for the crossover temperature, as mentioned above,
which derives from the difference in sign of the contributions of H., to the
magnetization. If we set Ho = 0, the crossover temperature is (II-3.2) T. = With hy;..

this distribution 1 — k = 0.79, thus reducing the contribution of the Gd3+ ions from
21 up to 17 un. Canting of the d-site Fe3+ ions, such that the 0.72 Fe" ion
moments are equivalent to 0.59 Fe3+ ion moments, further reduces the Gd3+ ion

In this case the nonuniformity of the anisotropy field, which arises because of the
differing orientation of M, with respect to the crystalline axes in the randomly
oriented polycrystalline grains, causes a contribution to the line width which is ...
