Magnetism of R2Ti3Ge4 (R=Sc, Gd, Tb, Dy, Ho, and Er) compounds
R. Nirmala,V. Sankaranarayanan,K. Sethupathi,G. Rangarajan,A.V. Morozkin,Darshan C. Kundaliya,Satish K. Malik +6 more
TL;DR: In this paper, the results of magnetization measurements down to 1.8 K on polycrystalline R2Ti3Ge4 (R=Sc, Gd, Tb, Dy, Ho, and Er) compounds of orthorhombic Sm5Ge4-type (space group Pnma) are presented and discussed.
Journal ArticleDOI
The order of magnetic phase transitions in disordered double perovskite oxides Sm2FeCoO6 and Dy2FeCoO6
TL;DR: In this article, the authors present the results on the order of phase transition around the spin re-orientation region using isothermal magnetization data performed on the sol-gel synthesized disordered double perovskite oxides Sm2FeCoO6 and Dy2FeO6 by Arrott plot method.
Journal ArticleDOI
Effect of Successive Multiple Doping of La, Nb and Fe on Structure and Lattice Vibration of MPB PZT
TL;DR: In this paper, the effect of successive multiple doping of La, Nb and Fe is analyzed by cumulative fitting of de-convoluted peaks, which represent various individual vibrational modes.
Journal ArticleDOI
Magnetic properties of Er2Mn3Si5
R. Nirmala,V. Sankaranarayanan,K. Sethupathi,A.V. Morozkin,Zili Chu,William B. Yelon,Satish K. Malik,Yoshihisa Yamamoto,Hidenobu Hori +8 more
TL;DR: In this paper, magnetization measurements have been carried out on the Er 2 Mn 3 Si 5 compound in the temperature range 1.8-300 K and the magnetic susceptibility in the paramagnetic region, above 100 K, follows simple Curie-Weiss type behavior.
Journal ArticleDOI
Particle size effect on magnetotransport properties of nanocrystalline Nd 0.7 Sr 0.3 MnO 3
TL;DR: In this paper, a spin dependent hopping between localized spin clusters together with the phase-separation phenomenon was analyzed by spin-dependent hopping between spin clusters and phase separation phenomenon, and the average cluster size in ferromagnetic phase is bigger than that in paramagnetic phase.
