摘要

The single crystals of Nd0.5Pr0.5FeO3 were successfully grown by optical floating zone method.Room temperature x-ray diffraction and Laue photograph declared the homogeneity and high quality of the crystal.The significant magnetic anisotropy and multiple magnetic transitions illustrate the complex magnetic structure.At high temperatures (T ＞ 66 K),it shows the typical characteristics of Γ4(Gx,Ay,Fz) state.With the decrease of the temperature,it undergoes a first-order spin reorientation transition fromΓ4(Gx,Ay,Fz) to F2(Fx,Cy,Gz) state in the temperature window of 45-66 K under an applied magnetic field of 0.01 T.As the temperature drops to ～ 17 K,a new magnetic interaction mechanism works,which results in a further enhancement of magnetization.The T-H phase diagram of Nd0.5Pr0.5FeO3 single crystal was finally constructed.
