摘      要：We have grown a YCrO_(3)single crystal by the floating-zone method and studied its temperature-dependent crystalline structure and magnetization by x-ray powder diffraction and PPMS DynaCool *** diffraction patterns were well indexed by an orthorhombic structure with space group of Pbnm(No.62).From 36 K to 300 K,no structural phase transition occurs in the pulverized YCrO_(3)single *** antiferromagnetic phase transition temperature was determined as T_(N)=141.58(5)K by the magnetization versus temperature *** found weak ferromagnetic behavior in the magnetic hysteresis loops below ***,we demonstrated that the antiferromagnetism and weak ferromagnetism appear simultaneously upon *** lattice parameters(a,b,c,and V)deviate downward from the Grüneisen law,displaying an anisotropic magnetostriction *** extracted temperature variation of the local distortion parameterΔ.Compared to theΔvalue of Cr ions,Y,O1,and O2 ions show one order of magnitude largerΔvalues indicative of much stronger local lattice ***,the calculated bond valence states of Y and O2 ions have obvious subduction charges.
