Spin reorientation and rare earth antiferromagnetic transition in single crystal Sm0.15Dy0.85FeO3
We report the crystal growth, structure analysis and magnetic phase transitions in the single crystal Sm0.15Dy0.85FeO3. The high-quality of the crystal is verified by X-ray diffraction technique. Our research reveals that: 1) the iron sublattice spin reorientation (SR) transition emerges at 25 K, and ends at 10 K; 2) the rare earth antiferromagnetic (AF) order transition happens at 2.6 K; 3) there is a special wasp-waist hysteresis loop at low temperatures. Knowledge of such phase transitions in rare earth orthoferrite system is of potential importance for applications and theoretical studies.
