摘要：

Magnetization of RAlO3 (R: Dy, Ho, and Er) single crystals along the c axis have been measured by the superconducting quantum interference device magnetometer. The single crystals are nominally pure and large sized, grown by the Czochralski method. Paramagnetic properties depend on the rare-earth elements. According to the magnetic entropy change, ErAlO3 single crystals are promising materials for the magnetic refrigerants using the Carnot cycle in the temperature range below 20 K. © 1995 American Institute of Physics.
