We report on effects of non-stoichiometry in GdtNixByCzsamples annealed at 800°C, with t=16.67% and t+x+y+z=100%. Every sample shows a peak at 12–13 K in the zero field cooled branch of the susceptibility curve merging with the field cooled branch at the same Néel temperature TN(Gd)=20.0(5) K. The magnetization at 5 K, M(H), and the paramagnetic behavior for all materials have been measured and in the limit of uncertainty all look the same. We conclude that the non-stoichiometry, up to 5%, on Ni, B and C sites does not affect magnetic ordering in this material and that the annealing temperature is very crucial for magnetic impurity phases. |
