Magnetic properties of the perovskite compounds YFe1–xCrxO3 (0.5≤x≤1)

Structure-Controllable Synthesis of Multiferroic YFeO3 Nanopowders and Their Optical and Magnetic Properties

“…Chemical doping is an effective way to improve the material properties and has been successfully used in YFeO 3 , including Mn and Cr doping at the Fe site [10,11] and Gd doping at Y site [12]. All the studies are related to the magnetic enhancement and not associated with the optical properties.…”

Hydrothermal synthesis and magnetic properties of REFe0.5Cr0.5O3 (RE = La, Tb, Ho, Er, Yb, Lu and Y) perovskite

“…11,12 While, only antiferromagnetic was found in the reported systems of REFe 0.5 Cr 0.5 O 3 (RE = La, Y and Nd), as Cr and Fe ions were randomly distributed at the B-sites in the bulk samples. [13][14][15] To date, studies on the REFe 1Àx Cr x O 3 system have been mainly focused on theoretical calculations. There are few methods for preparing REFe 1Àx Cr x O 3 single phases, as in the case of the ceramic method with repeated grinding and calcinations that the B-site Fe-Cr disorder is concomitant frequently and they separate into Fe oxide and Cr oxide phases.…”

Room temperature weak multiferroism and magnetodielectric effect in highly oriented (Y0.9Bi0.1)(Fe0.5Cr0.5)O3 thin films

“…Further, the observed values of the coercive field $550 Oe and the remanent magnetization $2.5 emu/cc suggest a weak ferromagnetic behavior of YBFCO film. This magnetic behavior of the film can be explained by considering the random distribution of canted nonequivalent spins of Fe 3+ and Cr 3+ in the octahedral sites which leads to a distribution of the weak ferromagnetic components inside the material [12,19]. However, such magnetization behavior can also be interpreted as ferrimagnetic like, possibly due to the dipolar interaction of Cr and Fe domains oriented in opposite directions [13].…”
