Yu, D., Huang, M., Wang, J. L., Su, H., Lin, H., Chen, C. & Campbell, S. J. (2014). Direct evidence of Ni magnetic moment in TbNi2Mn-X-ray magnetic circular dichroism. Journal of Magnetism and Magnetic Materials, 370 32-36.


We have investigated the individual magnetic moments of Ni, Mn and Tb atoms in the intermetallic compound TbNi2Mn in the Laves phase (magnetic phase transition temperature TC ∼131 K) by X-ray magnetic circular dichroism (XMCD) studies at 300 K, 80 K and 20 K. Analyses of the experimental results reveal that Ni atoms at 20 K in an applied magnetic field of 1 T carry an intrinsic magnetic moment of spin and orbital magnetic moment contributions 0.53±0.01 μB and 0.05±0.01 μB, respectively. These moment values are similar to those of the maximum saturated moment of Ni element. A very small magnetic moment of order
