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
Observation of spin glass state in weakly ferromagnetic Sr2FeCoO6 double perovskite
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.

Journal ArticleDOI
Electrical modulation of superconducting critical temperature in liquid-gated thin niobium films
TL;DR: In this paper, the superconducting critical temperature (Tc) of thin niobium films can be suppressed and enhanced by applying positive and negative gate voltage, respectively, in a reversible manner within a range of about 0.1
