摘要: The single crystals of Nd$_{0.5}$Pr$_{0.5}$FeO$_{3}$ 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 $\varGamma _{4}$(G$_{x}$, A$_{y}$, F$_{z}$) state. With the decrease of the temperature, it undergoes a first-order spin reorientation transition from $\varGamma _{4}$(G$_{x}$, A$_{y}$, F$_{z}$) to $\varGamma _{2}$(F$_{x}$, C$_{y}$, G$_{z}$) state in the temperature window of 45-66 K under an applied magnetic field of 0.01 T. As the temperature drops to $\sim 17 $ K, a new magnetic interaction mechanism works, which results in a further enhancement of magnetization. The ${T}$-$H$ phase diagram of Nd$_{0.5}$Pr$_{0.5}$FeO$_{3}$ single crystal was finally constructed.
