Magnetic excitations and exchange parameters of a nickel chain compound PbMnNiTeO: Neutron scattering and density functional theory studies
S. Uthayakumar, D. T. Adroja, Amit Pokhriyal +10
We have investigated the quasi-one dimensional Ni-chain compound PbMnNiTeO using theoretical DFT calculations, inelastic neutron scattering and optical spectrosc…
Optical bandgap and bowing parameter for Fe doped LaGaO3
P. R. Sagdeo, Preetam Singh, Hari Mohan Rai +3
The polycrystalline samples of LaGa1-xFexO3 have been prepared by standard solid state reaction route. The phase purity of the prepared samples is confirmed by powder xray diffract…
Room temperature magnetodielectric studies on Mn doped LaGaO3
Hari Mohan Rai, Ravikiran Late, Shailendra Saxena +4
The polycrystalline samples of LaGa1-xMnxO3 (0<x<0.3) has been prepared by solid state reaction route. The phase purity of these samples has been confirmed by powder x-ray diffract…
