Аннотация
The magnetic properties of substitutional solid solutions Eu0.9Yb0.1B6 have been investigated in the temperature range of 2–300 K in fields up to 5 T. The data obtained confirm that the state with the electronic and magnetic phase separation (typical of europium hexaboride) is implemented in Eu0.9Yb0.1B6 when the system metallization (TM ≈ 15 K) precedes the ferromagnetic ordering (TC ≈ 11.4 K). An analysis of the curves M(H) in the Belov–Arrott coordinates makes it possible to evaluate spontaneous magnetization Msp and zero field susceptibility χ0 and determine the character of their critical behavior near the Curie point. The calculated critical indices (γ ≈ 1.28 and β ≈ 0.34) are in agreement with the predictions of the three-dimensional Heisenberg model.
