摘要

合成了一种具有单相六方密排晶体结构的多组分稀土合金GdTbDyY。结果表明，该合金在温度为140和201 K时表现出两次磁相变。在包含这两种转变的温度范围内，存在明显的磁热效应。结果表明，GdTbDyY合金的磁性能主要由三价铽和镝离子贡献，结构参数与磁性参数之间存在相关性。

Structure and Magnetic Properties of the Medium-Entropy GdTbDyY Alloy

A multicomponent rare-earth alloy GdTbDyY with a single-phase hexagonal close-packed crystal structure was synthesized. It was found that this alloy exhibits two magnetic phase transitions at temperatures of 140 and 201 K. Within the temperature range that encompasses both transitions, there was a noticeable magnetocaloric effect. It was determined that the magnetic properties of the GdTbDyY alloy are mainly contributed by trivalent terbium and dysprosium ions: there is a correlation between structural and magnetic parameters.
