摘要	By using the high-order perturbation formulas, the g factors gvertical barvertical bar and gperpendicular to, the zero-field splittings D and the pressure and uniaxial stress dependences of zero-field splitting are studied for Ni2+ ions in both Mg2+ sites of La2Mg3(NO3)(12) . 24H(2)O crystal. It is found that the local trigonal distortion angles 2 of the two Ni2+ centers are only slightly different from the corresponding host ones, but the local angular compressibilities under pressure and stress for both Ni2+ centers are quite different not only from the corresponding host ones, but also from each other.
