Title: Mild hydrothermal synthesis and magnetic properties of the manganates Pr{sub 1-x}Ca{sub x}MnO{sub 3}

Abstract

The calcium-doped manganates, Pr{sub 1-x}Ca{sub x}MnO{sub 3} (x=0.39, 0.46, 0.70, 0.76), were synthesized as cube-shaped crystalline phases under mild hydrothermal conditions for the first time. The crystals could be grown in one step from solutions of metal salts and potassium hydroxide at temperatures {approx}240deg. C, and found to adopt perovskite-like structure (space group Pbnm). Samples were characterized by powder X-ray diffraction, scanning electron microscopy, inductively coupled plasma analysis and variable temperature dc/ac magnetic susceptibility. The studies indicate that formation of the materials is dependent on the alkalinity and composition of the initial reaction mixtures. The magnetic properties show spin-glass-like behavior due to competing ferromagnetic (FM) and antiferromagnetic (AFM) exchange interactions in Pr{sub 1-x}Ca{sub x}MnO{sub 3} with x=0.39, 0.46.
