Abstract
Magnetization and specific heat measurements were carried out on Pr0.9RE0.1Ni (RE = Tb, Dy, and Ho) single crystals. Spin rearrangements were observed along the \(c\)-axis of single crystals with relatively small critical fields, \(B_{\text{c}} = 6.8\), 4.0, and 2.6 T for RE = Tb, Dy and Ho, respectively. The magnetic phase transition temperatures, \(T_{\text{M}}\), were extracted from the specific heat data: \(T_{\text{M}} = 22.7\), 19.6, and 18.3 K with RE = Tb, Dy, and Ho, respectively. The observed \(B_{\text{c}}\) values were used to estimate the heterogeneous (Pr-RE) exchange strength, and then calculate expected \(T_{\text{M}}\) values, which were found to be close to the experimental ones. The present results of \(B_{\text{c}}\) and \(T_{\text{M}}\), together with the previous ones of Pr0.9Gd0.1Ni, were found to be consistent with the de Gennes rule.
