用真空高频磁悬浮炉制备了Gd3Al2、Gd2.9Zn0.1Al2、Gd2.7Zn0.3Al2、Gd2.4Zn0.6Al2四种合金.用直接测量法测量了在1.5T磁场下这四种合金的磁热效应.结果表明,在1.5T磁场下,Gd3Al2、Gd2.9Zn0.1Al2、Gd2.7Zn0.3Al2、Gd2.4Zn0.6Al2的最大绝对温变分别为2.0K、1.4 K、1.1K和0.7K;当Zn含量为0.1时,居里温度为287K.
用真空高頻磁懸浮爐製備瞭Gd3Al2、Gd2.9Zn0.1Al2、Gd2.7Zn0.3Al2、Gd2.4Zn0.6Al2四種閤金.用直接測量法測量瞭在1.5T磁場下這四種閤金的磁熱效應.結果錶明,在1.5T磁場下,Gd3Al2、Gd2.9Zn0.1Al2、Gd2.7Zn0.3Al2、Gd2.4Zn0.6Al2的最大絕對溫變分彆為2.0K、1.4 K、1.1K和0.7K;噹Zn含量為0.1時,居裏溫度為287K.
