Co-existence of magnetocaloric effect and magnetoresistance in Co substituted La0.67Sr0.33MnO3 at room temperature

Reshmi, C P; Savitha Pillai, S; Vasundhara, M; Raji, G R; Suresh, K G; Manoj Raama Varma (American Institute of Physics, 2013)

Magnetization (M), Magnetocaloric effect (MCE), and Magnetoresistance (MR) in Co substituted La0.67Sr0.33Mn1-xCoxO3 (x = 0.03, 0.05, and 0.1) samples have been investigated. All the studied samples were crystallized into ...
Influence of cobalt on the structural, magnetic and magnetocaloric properties of La0.67Ca0.33MnO3

Nisha, P; Savitha Pillai, S; Manoj Raama Varma; Suresh, K G (Elsevier, 2013)

The critical properties and magnetocaloric effect of perovskite manganite La0.67Ca0.33Mn1-xCoxO3 (x=0.03, 0.1 and 0.15) are investigated. Structural study using Reitveld refinement of X-ray diffraction pattern indicates ...
Near room temperature magnetocaloric properties of Fe substituted La0.67Sr0.33MnO3

Reshmi, C P; Savitha Pillai, S; Suresh, K G; Manoj Raama Varma (Elsevier, 2013)

The effect of Fe substitution in the polycrystalline La0.67Sr0.33MnO3 has been investigated. Substitution of Fe decreases the Curie temperature of La0.67Sr0.33MnO3 from 370 K to near room temperature in x < 0.3 samples, ...
Re-entrant spin glass behaviour and magneto-dielectric effect in insulating Sm2NiMnO6 double perovskite

Neenu Lekshmi, P; Raji, G R; Vasundhara, M; Manoj Raama Varma; Savitha Pillai, S; Valant, M (Royal Society of Chemistry, 2013)

The structure and magneto-dielectric properties of Sm2NiMnO6 double perovskite have been investigated. The pure monoclinic bulk phase of Sm2NiMnO6 is an intrinsic B-site disordered ferromagnet showing a second order magnetic ...
Synthesis of chemically pure, luminescent Eu3+ doped HAp nanoparticles: A promising fluorescent probe for in vivo imaging applications.

Hasna, K; Sasanka Kumar, S; Komath, M; Manoj Raama Varma; Jayaraj, M K; Rajeev Kumar, K (Royal Society of Chemistry, 2013)

The poor solubility, poor biocompatibility and disposal issues make fluorescent quantum dots such as CdSe, CdS, ZnS, InP, InAs, etc. impractical for imaging tissues or intercellular structures. As calcium phosphate is the ...
