Magnetic, Magnetocaloric and Magnetoresonance Properties of (1-x)La_0.7Sr_0.3MnO₃/xGeO₂ (x=0, 0.15)

Abstract:

0.85La_0.7Sr_0.3MnO₃/0.15GeO₂ composite material and pure La_0.7Sr_0.3MnO₃ were investigated by X-ray diffraction, scanning electron microscopy, magnetometry and magnetic resonance methods. It was observed that both samples demonstrate the ferromagnetic properties, while the absolute value of the magnetization, the magnetic entropy change and the magnetic ordering temperature decrease in composite in comparison with pure La_0.7Sr_0.3MnO₃. The magnetic resonance spectra of investigated (1-x)La_0.7Sr_0.3MnO₃/xGeO₂ (x=0, 0.15) can be attributed to the superposition of magnetic resonance spectra from magnetically anisotropic particles with different orientations.
