Magnetic properties of La0.7Ca0.3MnO3 nanoparticles prepared by reactive milling

Low-field magnetoresistance of La0.7Ca0.3MnO3 perovskite synthesized by reactive milling method

“…La2O3, CaCO3 and MnO2 powders with purity 99.9% from Merck were used as the starting materials. Phase-pure completely LCMO powders obtained after 8 h of milling time in the ambient atmosphere [15]. Finally, the resulting powder was pressed into circular pellets and annealed at 600 • C (S1), 650 …”

La0.7Ca0.3MnO3 perovskite synthesized by reactive milling method: The effect of particle size on the magnetic and electrical properties

“…detail reported in [13]). Finally, the resulting powder was pressed into circular pellets and annealed at 700, 750, 800, 900 and 1000 • C (in air 5 h).…”

“…In our previous works [8,12,13], we have presented experiment results and theoretical analysis on magnetic properties of La 0.7 Sr 0.3 MnO 3 and La 0.7 Ca 0.3 MnO 3 nanoparticles synthesized by reactive milling with various milling time. In this paper, we report the effect of annealing temperature on microstructure, magnetic and electrical properties of La 0.7 Ca 0.3 MnO 3 nanoparticles synthesized by the same method.…”

The influence of the heat treatment on the structural and magnetic properties of nanoparticle La0.7Ca0.3MnO3 prepared by glycine–nitrate method

“…Perovskite manganites have been systematically investigated in the form of bulk, single crystal and thin film [1,2], while manganites at the nanometer scale recently become the subject of intense research [3][4][5][6][7][8][9][10][11]. From the magnetic viewpoint, the nanoparticle manganites usually exhibit qualitatively new properties, such as changes in magnetic transition temperatures, the emergence of superparamagnetism, size dependence of the saturation magnetization and coercivity, etc.…”
