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

A low temperature, one-pot route to iron-doped rare-earth chromite perovskite was proposed. Fe half-doped rare-earth chromites, REFe 0.5 Cr 0.5 O 3 (RE = La, Tb, Ho, Er, Yb, Lu and Y) were prepared via a mild hydrothermal method and their magnetic properties were studied. All of these materials are...

Description
Summary:A low temperature, one-pot route to iron-doped rare-earth chromite perovskite was proposed. Fe half-doped rare-earth chromites, REFe 0.5 Cr 0.5 O 3 (RE = La, Tb, Ho, Er, Yb, Lu and Y) were prepared via a mild hydrothermal method and their magnetic properties were studied. All of these materials are well-crystallized and the profile refinement of powder X-ray diffraction (XRD) data showed that each of them adopts an orthorhombic distorted ( Pbnm ) perovskite structure. The temperature dependence of the magnetization curves indicate an improved order of arrangement of Fe 3+ and Cr 3+ at the B-site in some samples. Hysteresis measurements of YFe 0.5 Cr 0.5 O 3 indicate that saturated and remnant magnetization were improved greatly compared to that prepared via the solid state method. Unit cell parameters are gradually changing with increasing RE 3+ radii. Hysteresis of YFe 0.5 Cr 0.5 O 3 shows greater maximum and remnant magnetization.
