Re-entrant spin glass behaviour and magneto-dielectric effect in insulating Sm2NiMnO6 double perovskite
TL;DR: In this article, the structure and magneto-dielectric properties of Sm2NiMnO6 double perovskite have been investigated, and the authors define this ferromagnetic insulator as a relaxor-type dielectric material.
Journal ArticleDOI
Observation of high-temperature magnetic transition and existence of ferromagnetic short-range correlations above transition in double perovskite La2FeMnO6
TL;DR: In this paper, the authors present the observation of a high-temperature magnetic transition along with ferromagnetic short-range correlations (FSCs) in La2FeMnO6 perovskite system.
Journal ArticleDOI
Room temperature relaxor ferroelectricity and spin glass behavior in Sr2FeTiO6 double perovskite
TL;DR: In this paper, the structure, dielectric and magnetic properties of complex Sr2FeTiO6 double perovskite have been investigated and the relaxor behavior has been quantitatively characterized based on phenomenological parameters (Tm, TB, γ, ΔTrelax).
Journal ArticleDOI
Competing short-range magnetic correlations, metamagnetic behavior and spin-phonon coupling in Nd2CoMnO6 double perovskite
TL;DR: In this paper, the presence of ferromagnetic short-range interactions, metamagnetic transitions and spin-phonon coupling on monoclinic polycrystalline Nd 2 CoMnO 6 double perovskite was reported.
Journal ArticleDOI
