"Magnetoresistive ceramic samples La0.7Ca0.3 - xSrxMnO3 +/- delta sintered at temperatures of 1150 and 1350 degrees C are investigated using X-ray diffraction, microscopic, resistance, and magnetic (chi, Mn-55 NMR) measurements," researchers in Donetsk, Ukraine report.
"The specific features of the influence of the composition on the type and parameters of the perovskite structure, its imperfection, the porous crystallite structure, the metal-semiconductor and ferromagnetic-paramagnetic phase transitions, the Mn-55 NMR spectra, and the magnetoresistance effect are established. The magnetic phase diagram is constructed," wrote A.V. Pashchenko and colleagues.
