Title: Structural and magnetic properties of high-pressure/high-temperature synthesized (Sr{sub 1-x}R{sub x})CoO{sub 3} (R=Y and Ho) perovskites

Abstract

Polycrystalline perovskite cobalt oxides Sr{sub 1-x}R{sub x}CoO{sub 3} (R=Y and Ho; 0=<x=<1) were prepared by high-pressure/high-temperature technique. X-ray powder patterns of the Y-system indicated cubic perovskite form for 0=<x=<0.5, and orthorhombic perovskite form for x=0.8 and 1.0, while coexisting of the two phases for x=0.6. The cubic perovskite samples had metallic electric resistivities while the orthorhombic ones with semiconducting or insulating nature. The parent compound SrCoO{sub 3} showed a ferromagnetic transition at 266K. With the Y substitution, the transition temperature increased slightly to {approx}275K at x=0.1, then decreased rapidly to {approx}60K for x=0.6. The YCoO{sub 3} (x=1) sample showed non-magnetic behavior. The Ho-substituted system showed quite similar structural, transport and magnetic properties to those of the Y-system.
