The effect of Fe doping in the Mn site on the magnetic, transport and structural properties of
polycrystalline La1/2Ca1/2MnO3 was studied. Doping with low Fe concentration (< 10%) …

The effect of doping a magnetic ion like Co and a non-magnetic ion like Ga at the Mn-site in
La0. 7Ca0. 3MnO3 was studied. ac magnetic susceptibility (χ) measurements show a large …

We investigate the effects of calcium deficient on the structural and magnetotra□ nsport
properties of non‐stoichiometric La0. 5Ca0. 5− x□ xMnO3 manganese oxides. Powder …

A systematic study of the magnetic and transport properties of the system (La1− xGdx) 0.67
Ca0. 33MnO3 (0⩽ x⩽ 1) is presented in this article. Through this series, a great …

Emission Mössbauer effect investigations were done simultaneously with resistivity
measurements on two similar samples of La 0.8 Ca 0.2 Mn (57 Co) O 3, in one of which 18 O …

Polycrystalline La0. 7Ca0. 3MnO3− δ (LCMO), prepared by a solid-state reaction, was
annealed at different temperatures TA. The variation of TA was responsible for observed …

We have prepared new perovskite manganites La0. 7Ca0. 3− xKxMnO3 (0⩽ x⩽ 0.15).
These compounds are shown to undergo structural transition from orthorhombic to …

We report anomalous post-annealing effects of La0. 8Ca0. 2MnO3 under O2 and Ar
atmospheres. We have found that the critical temperature (TC) of the as-prepared sample …
