Journal ArticleDOI
Significant enhancement of magnetoresistance with the reduction of particle size in nanometer scale.
TL;DR: This study on several manganite samples illustrates the method of significant enhancement of MR with the reduction of the particle size in nanometer scale and shows the method will have enormous potential for magnetic field sensor technology.
Journal ArticleDOI
Giant spontaneous exchange bias effect in Sm 1.5 Ca 0.5 CoMnO 6 perovskite
TL;DR: In this article, the spontaneous exchange bias (SEB) in the Sm1.5Ca0.5CoMnO6 bulk double perovskite system after zero-field cooling from an unmagnetized state was reported.
Journal ArticleDOI
Field induced ferromagnetic phase transition and large magnetocaloric effect in Sm0.55Sr0.45MnO3 phase separated manganites
TL;DR: In this article, the magnetocaloric effect and relative cooling power based on the first order magnetic phase transition in Sm 0.55 Sr 0.45 MnO 3 polycrystalline phase separated manganites were reported.
Journal ArticleDOI
Antisite-disorder driven large exchange bias effect in phase separated La 1.5 Ca 0.5 CoMnO 6 double perovskite
TL;DR: In this article, a phenomenological model has been proposed to explain the exchange coupling between the ferromagnetic and canted-antiferromagnetic interfaces of antisite-disordered double perovskite La 1.5 Ca 0.5 CoMnO 6 mainly on the basis of uncompensated interface spins.
Journal ArticleDOI
