The present work reports a comprehensive investigation of the structural, magnetic, and transport behaviors of the rare-earth indium-based intermetallics Gd5In3 and Tb5In3. The high-temperature paramagnetic-to-ferromagnetic transitions in both the compounds are found to be second order, obeying a mean-field type critical behavior. The sample shows multiple low-temperature anomalies and clear signatures of thermal hysteresis are observed in the magnetization versus temperature data in the vicinity of such transitions. Tb5In3 shows a moderate amount of magnetocaloric effect around its high-temperature Curie point. Interestingly, Gd5In3 shows large negative magnetoresistance at low temperatures, which is comparable to many other bulk intermetallic compounds.

Gd5In3 和 Tb5In3 化合物的磁性、磁热效应和磁阻效应
目前的工作报告了对稀土铟基金属间化合物 Gd 5 In 3和 Tb 5 In 3的结构、磁性和传输行为的综合研究。发现这两种化合物的高温顺磁到铁磁转变都是二阶的，服从平均场型临界行为。该样品显示出多个低温异常，并且在这种转变附近的磁化强度与温度数据中观察到明显的热滞现象。Tb 5 In 3在其高温居里点附近显示出适度的磁热效应。有趣的是，Gd 5 In 3在低温下显示出大的负磁阻，这与许多其他大块金属间化合物相当。
