Magnetic Moment Versus Temperature Curves of Ferrimagnetic Garnet Materials

Abstract

The molecular field coefficients employed in the Neel theory of ferrimagnetism have been determined as functions of the levels of diamagnetic ion substitution in the garnet family (Y(z)Gd(3-z))(R(x)Fe(2-x))(Q(y)Fe(3-y)) O(12), where R and Q represent diamagnetic octahedral and tetrahedral substitutions, respectively. With these coefficients the magnetic moment versus temperature curves of compositions ranging from 0 = or < x = or < 0.70, 0 = or < y = or < 1.95, and 0.40 = or < z = or < 1.00 were computed and are presented in this report.
