- Abstract
- Single-crystalline DyFe1-x Mn (x) O-3 perovskites with the nominal Mn contents of x = 0.2, 0.5, and 0.7 were grown successfully. The solid solutions have an orthorhombic structure with space group Pbnm. Magnetic susceptibilities at different crystallographic axes show a large magnetic anisotropy, primarily originating from the large spin-orbit coupling of the Dy moment. For DyFe0.8Mn0.2O3, a room-temperature weak ferromagnetism is confirmed along the c-axis. A spin reorientation transition occurs at T (SR) a parts per thousand 225 K, below which the canted weak ferromagnetic moment disappears. The application of a high magnetic field (A mu H-0 a parts per thousand yen 6 T) along the c-axis at T = 200 K unveils a hidden field-induced weak ferromagnetism, which probably has the same spin configuration as that above T (SR) a parts per thousand 225 K.
