Critical behaviors of the nonlinear susceptibility in spin glasses have been extensively studied by various experiments and numerical calculations. It has been suggested from both experimental (1,2) and theoretical (3) points of view that the anisotropy in real systems plays an important role for the presence of spin-glass transition and the scaling behavior in the nonlinear susceptibility. Recently, we have studied the uniaxially anisotropic spin-glass ZnMn (4,5) over a wide range of the Mn impurity concentration. Since in ZnMn it is possible to control the ratio of the anisotropy to the variance of the random exchange interaction (D/J) by changing the Mn concentration, systematic study for the effect of the uniaxial anisotropy D on the spin-glass critical behavior could be done in this system.
