Abstract:
The magnetic and electrical transport properties of Tb4PtAl, crystallizing in the Gd4RhIn-type cubic crystal structure characterized by three sites for the rare-earth, are reported by the measurements of magnetization, heat-capacity, and electrical resistivity (1.8–300 K). In comparison with the Gd analog, which has been shown to exhibit a complex magnetism with antiferromagnetism (TN = 64 K) entering into a spin-glass phase below 20 K, the spin-glass phase coexists at the onset of the antiferromagnetic order at 50 K in the Tb compound; additional spin-glass anomalies around 8 and 25 K are also found. Interestingly, the plot of electrical resistivity vs temperature develops a minimum in the presence of an external magnetic field above 50 K, and this transport behavior, unusual among rare-earth intermetallics, is presumably due to the gradual growth of short-range antiferromagnetic clusters as the long-range magnetic order develops.
