“…It behaves as a weak ferromagnet, with a spontaneous moment appearing only along the b axis. 8 It presents a G-type magnetic arrangement below T N = 140 K as established by Bertaut using neutron powder diffraction. 9 Recently, YCrO 3 has been considered a potential multiferroic compound.…”

Temperature- and magnetic-field-induced magnetization reversal in perovskite YFe0.5Cr0.5O3

“…The best fit of the observed diffraction peaks is obtained with the orthorhombic structure with space group Pnma, which is the same as that of the end members YFeO 3 and YCrO 3 . 11,12 The calculated lattice parameters are a = 5.4987͑1͒ Å, b = 7.9786͑5͒ Å, and c = 5.5142͑3͒ Å, respectively. The crystallographic data are similar to the neutron diffraction data as Azad et al 10 reported in LaFe 0.5 Cr 0.5 O 3 , which also did not show any signal of ordering between Fe 3+ and Cr 3+ cations in these perovskite oxides.…”

“…This kind of magnetization loop and the linear dependence at high field are usually attributed to the weak ferromagnetism caused by a departure from the collinearity of the moments in an antiferromagnet. 8,12,13 The high field part of M͑H͒ curves can be represented as M = AFM H + S , where AFM H is the antiferromagnetic ͑AFM͒ contribution and S is the saturation magnetization of the weak ferromagnetism. Thus, the ferromagnetic component in YFe 0.5 Cr 0.5 O 3 can be obtained by subtracting the AFM contribution from the total magnetization.…”

Resonant and non-resonant microwave absorption in the magnetoelectric YCrO3 through ferro-paraelectric transition

“…Industrial applications of the YCrO 3 perovskite include its use as interconnection for the solid oxide fuel cells [12], while in pure science it has been applied to develop a model for defective structures [13]. Additionally, this compound is an antiferromagnet with a weak ferromagnetism below T N = 140 K [14][15][16][17]; where the Cr 3+ (S = 3/2) ion is of primary importance for the magnetic properties of this material. Also, the YCrO 3 perovskite is an intriguing ferroelectric material, since the existence of ferroelectricity for their centrosymmetric crystalline structure (Pbnm) [16,18]; with a Curie temperature (T C ) in the 410-450 K range [16,19].…”
