摘要：

Magnetization and torque magnetization measurements, together with the results of electron paramagnetic resonance experiment, were conducted on the Pr0.50+xSr0.50-xMnO3 single crystals. Orbital-order-induced strong magnetic anisotropy is found in the ferromagnetic (FM) state. It is observed by torque magnetization that magnetic anisotropy exists even in the paramagnetic (PM) and antiferromagnetic (AFM) states, indicating existence of the FM cluster in the A-type AFM state below the FM-AFM transition temperature and the PM state far above the Curie temperature. The results prove that the interplay of spin and orbital results in intrinsic phase separation in the manganite systems. (c) 2006 American Institute of Physics.
