摘要：

YTiO3 has been known as a Mort-insulating ferromagnet with the Curie temperature T-c = 30 K. We have measured the magnetization of single crystals of Y1-xCaxTiO3 (x = 0, 0.01. 0.02, 0.05, 0.10) grown by a floating-zone method. In YTiO3. a metamagnetic-like transition was observed for B\\a and B\\c (easy axis) at 1.5 and 7.5 mT, respectively. only after zero-field cooling. For B\\b (hard axis), however, no metamagnetic behavior appears. From the magnetization measurements of alloys, it is found that the anisotropy in magnetization for B\\a and B\\c vanishes with increasing x up to 0.1. (C) 2000 Elsevier Science B.V.
