Abstract

The magnetic susceptibility χ of nickel diglycine dihydrate has been measured between 0.6 and 120 K. The high-temperature data were taken in powder and follow a Curie law behavior with μeff = 3.189 μB and an antiferromagnetic Curie temperature TC = 2.47 K. At low temperatures the χ vs temperature curves for powder and oriented single crystals deviate from the Curie law; they show a maximum χ at about 2.21 K and an abrupt decrease at lower temperatures. The observed behavior of χ for nickel diglycine dihydrate indicates dominating antiferromagnetic interactions between Ni ions. A phase transition to an antiferromagnetic phase occurs below 2.2 K.
