摘要: Abstract The magnetic behaviors of the paramagnetic dysprosium gallium garnet (DyGaG) are theoretically investigated in terms an extensional molecular-field theory. contribution exchange interaction between ions to properties DyGaG is further explored. Here, as DyGaG, our model, two sublattices A and B suggested. corresponding discussed, it found that χ > DyGaG. Meanwhile, field coefficients λ 1 2 qualitatively analyzed. optimum fitting parameters α associated with provided, some interesting conclusions about these drawn. Then, available experiments successfully fitted by theoretical model. Additionally, analysis high-field presented.
