Griffiths phase-like behavior and spin-phonon coupling in double perovskite Tb2NiMnO6
Harikrishnan S. Nair,Diptikanta Swain,N Hariharan,Shilpa Adiga,Chandrabhas Narayana,Suja Elzabeth +5 more
TL;DR: In this article, the Griffiths phase-like features and spin-phonon coupling effects observed in Tb(2)NiMnO(6) are reported and a negative deviation from ideal Curie-Weiss law exhibited by 1/chi(T) curves and less-than-unity susceptibility exponents from the power-law analysis of inverse susceptibility are reminiscent of Griffiths phases.

Magnetization-steps in Y2CoMnO6 double perovskite: The role of antisite disorder
Harikrishnan S. Nair,R. Pradheesh,Yinguo Xiao,Dona Cherian,Suja Elizabeth,Thomas C. Hansen,Tapan Chatterji,Th. Brückel +7 more
TL;DR: In this paper, a paramagnetic-ferromagnetic phase transition occurs in the double perovskite Y2CoMnO6 which has been recently identified as a multiferroic.
Journal ArticleDOI
Exchange bias and memory effect in double perovskite Sr2FeCoO6
TL;DR: In this paper, the exchange bias and memory effect in double perovskite Sr2FeCoO6 was observed and the spin glass transition temperature, Tg, versus Hdc2/3, followed the Almeida-Thouless line yielding a freezing temperature of Tf=73K.
Journal ArticleDOI

R. Pradheesh,Harikrishnan S. Nair,C. M. N. Kumar,Jagat Lamsal,R. Nirmala,P. N. Santhosh,William B. Yelon,S. K. Malik,V. Sankaranarayanan,K. Sethupathi +9 more
TL;DR: In this paper, a spin glass state is observed in the double perovskite oxide Sr2FeCoO6 prepared through sol-gel technique, which shows that the compound crystallizes in tetragonal I4/m structure with lattice parameters.
