Abstract
The magnetic anisotropy of the title compound has been determined from 4.58 to 300 K and the average suscepti-bility has been measured down to 1.98 K at field strengths ranging from 10 to 50 kG. The results are interpreted on a point-charge model for D3d symmetry using the parameters A2 0〈r2〉=925 cm–1. ρ4= 4 920 cm–1, F2= 1 306 cm–1, F4= 93 cm–1, ζ= 550 cm–1, and k= 1.0. It is suggested that the trigonal distortion of the nickel ion increases as the temperature is decreased to 100 K. The low-temperature anisotropy and magnetization are consistent with the compound being antiferromagnetic with TN < 2 K.Keywords
