Abstract

We measured the magnetization up to 30T, specific heat and electrical resistivity for the Er1.2Fe4Si9.8 single crystal, which has a two-dimensional layer structure. In the magnetic susceptibility measurements, a broad peak was observed at 1.7 K for H || a. Magnetization curve for the a-axis shows a spin-flop behavior at 0.4 T below 1.6 K. For the c-axis, a broad peak appears at 10 T in the differential magnetization curve, suggesting the energy level crossover. No clear magnetic ordering was confirmed although the specific heat shows a small anomaly at 1.5 K, a peak at 0.96 K and a shoulder at 0.67 K.
