Competing short-range magnetic correlations, metamagnetic behavior and spin-phonon coupling in Nd2CoMnO6 double perovskite
چکیده انگلیسی
We report the presence of ferromagnetic short-range interactions, metamagnetic transitions and spin-phonon coupling on monoclinic polycrystalline Nd2CoMnO6 double perovskite. DC thermomagnetic characterization shows a paramagnetic to ferromagnetic transition at TC1∼168 K and further to a cluster glass like magnetic transition at TC2∼135 K. Griffiths phase like features are also observed, attributed to the presence of competing magnetic interactions. Step like nature observed in the virgin curves of magnetic isotherms implies the presence of metamagnetic features. Additionally, temperature evolution of Raman spectra signatures spin-phonon coupling extending up to Griffiths like phase region indicating the possibility of magnetoelectric coupling in Nd2CoMnO6.
