Observation of spin glass state in weakly ferromagnetic SrFeCoO double perovskite
R. Pradheesh, Harikrishnan S. Nair, C. M. N. Kumar +7
We report the observation of spin glass state in the double perovskite oxide SrFeCoO prepared through sol-gel technique. Initial structural studies using x rays reveal…
Anomalous magnetic and transport properties of La(0.8-x)Eu(x)Sr0.2MnO3 (0.04 l.e. x l.e. 0.36) compounds
Rakesh Kumar, C. V. Tomy, P. L. Paulose +2
Anomalous magnetic and transport properties observed in the La0.8-xEuxSr0.2MnO3 (0.04 l.e x l.e. 0.36) compounds are presented in this paper. The Curie temperature (TC) decreases f…
Magnetocaloric effect in R2Ti3Ge4 (R = Gd, Tb and Er) Compounds
R. Nirmala, Darshan C. Kundaliya, A. V. Morozkin +1
Heat capacity of polycrystalline R2Ti3Ge4 (R = Gd, Tb and Er) compounds (Orthorhombic, Sm5Ge4-type, Space group Pnma) has been studied in the temperature range of 1.8 K to 300 K in…
Enhancement of flux pinning and high critical current density in graphite doped MgB2 superconductor
Chandra Shekhar, Rajiv Giri, R. S. Tiwari +2
We report the synthesis and characterization of graphite (C) doped MgB2-xCx (x = 0.0, 0.1, 0.2 and 0.3) samples. The crystal structure and microstructural characterization have bee…
Tuning the Competing magnetic interactions in RTiGe (R = Tb, Er) Compounds and tailoring the Magnetocaloric effect
R. Nirmala, S. K. Malik
The tetragonal layered compounds TbTiGe and ErTiGe order antiferromagnetically at 276 K and 39 K, respectively. Partial substitution of Mo for Ti in these two compounds modifies th…
Magnetic, magneto-thermal and magneto-transport properties in SmMn2Si2-xGex compounds
Pramod Kumar, K. G. Suresh, A. K. Nigam +1
The effect of Ge substitution for Si in SmMMn2Si2-xGex compounds has been studied. The Sm ordering temperature is found to be much larger in the compound with x=2, as compared to t…
