Polycrystalline insulating ferromagnetic double perovskite La2CoMnO6 possessing monoclinic structure and a high ferromagnetic Curie temperature (TC = 222 K) was rapidly synthesized ( 30 min) by irradiating stoichiometric mixture of oxides…

Ferromagnetic metallic oxides have potential applications in spincaloric devices which utilize the spin property of charge carriers for interconversion of heat and electricity through the spin Seebeck or the anomalous Nernst effect or both.…

Magnetization has been measured for polycrystalline samples of LaCo1-xRhxO3 (0 {\leq} x {\leq} 0.9) in order to investigate magnetism induced in the solid solution of two nonmagnetic end phases of LaCoO3 and LaRhO3. It is found that a…

We report microwave-assisted synthesis and physical properties of La-doped SrCoO3-{\delta}. The Sr0.8La0.2CoO3-{\delta} synthesized via microwave heating (MWH) exhibits superior physical properties compared to a nominally identical…

Employing a broadband microwave reflection configuration, we have measured the complex surface impedance, $Z_S(\omega,T)$, of single crystal La$_{0.8}$Sr$_{0.2}$MnO$_3$, as a function of frequency (0.045-45 GHz) and temperature (250-325 K).…

Co10Ge3O16 crystallizes in an intergrowth structure featuring alternating layers of spinel and rock salt. Variable-temperature powder synchrotron X-ray and neutron diffraction, magnetometry, and heat capacity experiments reveal a…

Magnetic, linear thermal expansion (LTE), anisotropic ($\lambda_t$) and volume ($\omega $) magnetostriction properties of Pr$_{0.5}$Sr$_{0.5}$MnO$_3$ were investigated. The LTE decreases smoothly from 300 K without a clear anomaly either…

Bulk magnetodielectric composites with a 3/0 configuration comprising of ferroelectric/magnetostrictive phases have been synthesized using Sr0.5Ba0.5NbO6 / CoCr0.4Fe1.6O4 as the two constituents respectively. The ferroelectric phase made by…

Neutron diffraction studies have been carried out on a single crystal of oxygen-deficient perovskite TbBaCo2O5.5 in the temperature range of 7-370 K. There have been observed several magnetic or structural transitions. Among these, the…

We report electrical, magnetic, magnetodielectric and magnetoabsorption properties of a polycrystalline GaFeO3. The resistivity measurement shows that the sample is highly insulating below 200 K and the resistivity above 200 K obey the…

In this study we examine the phase transitions in single crystals of [(CH3)2NH2]Co(HCOO)3], using magnetization and specific heat measurements as a function of temperature and magnetic field. Magnetisation measurements indicate a transition…

The resistive and reactive parts of the magneto-impedance of sintered ferromagnetic samples of La0.7Sr0.3-xAgxMnO3 (x = 0.05, 0.25) have been measured at room temperature (<Tc) over frequency interval 1KHz to 15MHz and in presence of…
