Abstract

Temperature dependence of electrical resistivity, ρ, was measured for Gd1-xYxMn2Ge2 with 0≤x≤0.5 from 4.2K to room temperature. For 0≤x≤0.3, a step was observed in the ρ-T curve, which is associated with a first-order magnetic transition from a high-temperature antiferromagnetic (AF) state to a low-temperature ferrimagnetic (Fi) state. On the other hand, the ρ-T curve of x=0.5 shows an inflection at low temperatures, which is an indication of a magnetic transition from a high-temperature antiferromagnetic state to a low-temperature canted ferrimagnetic (CF) state. Both a step and an inflection were observed in the ρ-T curve of x=0.4. These results have demonstrated that the compound undergoes successive AF-CF-Fi transitions in the cooling sequence, which was proposed by early magnetization measurements.
