Title: Improvement of the Magnetization and Coercivity of La{sub 0.67}Ca{sub 0.33}MnO{sub 3} Induced by Substitution of Nickel for Manganese

Abstract

La{sub 0.67}Ca{sub 0.33}Mn{sub 1−x}Ni{sub x}O{sub 3} (0 ≤x ≤ 0.3) is synthesized by solid-state reaction at low temperatures, followed by calcination in air. The precursor and its calcined products are characterized by thermogravimetry and differential scanning calorimetry, x-ray powder diffraction, scanning electron microscopy, and vibrating sample magnetometer. A high-crystallized La{sub 0.67}Ca{sub 0.33}Mn{sub 1−x}Ni{sub x}O{sub 3} with an orthorhombic structure is obtained when the precursor is calcined at 900{sup ∘}C in air for 3 h. Crystallite size of La{sub 0.67}Ca{sub 0.33}Mn{sub 1−x}Ni{sub x}O{sub 3} increases with the increase of Ni content, attributed to the decrease of lattice strains of the La{sub 0.67}Ca{sub 0.33}Mn{sub 1−x}Ni{sub x}O{sub 3} with the increase in Ni content. Nickel substitution can markedly improve coercivity and specific magnetization of La{sub 0.67}Ca{sub 0.33}Mn{sub 1−x}Ni{sub x}O{sub 3}. The coercive field (9 Oe) of La{sub 0.67}Ca{sub 0.33}Mn{sub 0.7}Ni{sub 0.3}O{sub 3} is higher, even at 293 K, indicating that La{sub 0.67}Ca{sub 0.33}Mn{sub 0.7}Ni{sub 0.3}O{sub 3} continues being ferromagnetic above 260 K (Curie temperature for LCMO).
