Abstract
Powdered samples of β-Ni(trz)2(NCS)2 have been investigated by measurements of the magnetic susceptibility (in the temperature range T = 15-300 K), magnetization (at T = 4.2 K) and heat capacity (T = 1-90 K). From the magnetization measurements the material is found to be a weak ferromagnet, with a zero-field magnetic moment of ~ 0.015 μB. The ordering temperature is determined as Tc = 10.14(2) K. The susceptibility and heat capacity data are in reasonable agreement with predictions from high-temperature series expansions for the quadratic layer, S = 1, Heisenberg antiferromagnet, with an intralayer exchange constant J/k = - 4.5(1) K.Keywords
