研制了TbAlO3及相关磁性材料的几种样品。这些材料具有大的磁矩，并且大多数在4K以下表现出磁相变。用绝热热脉冲法测量了所有样品的热容。研究了热容量与制备温度的关系。讨论了这些材料作为脉管制冷机回热材料的可能性。
Several samples of TbAlO3 and related magnetic materials were developed. These materials have large magnetic moment, and most of them exhibit the magnetic phase transition below 4K. The heat capacity of all samples has been measured with the adiabatic heat-pulse method. The dependence of the heat capacity on the preparation temperature has been studied. We discussed possibility of using these materials as regenerator materials in pulse tube refrigerator.
