In this work we demonstrate that La2NiMnO6 exhibits a colossal magneto-dielectric (MD) effect (5%-55%) over a broad range of temperatures (100–270 K), when compared to other Rare Earth (RE = Pr, Sm, and Tb) containing Ni-Mn double perovskites. The noticeable magneto-dielectric effect in RE2NiMnO6 signals the influence of spin orientations in the two magnetic sublattices on the spin-lattice coupling. Finally with the help of Raman spectroscopy we clarify that the presence of spin-phonon coupling alone is not the cause for the observed colossal MD effect in RE2NiMnO6.

Temperature-field and orientational magnetization dependences of single crystals were measured. Both samples demonstrate significant field-depending temperature hysteresis and low-temperature counter field magnetization. The correlation of orientational dependences of these effects and magnetic anisotropy is analyzed; the role of spin-lattice interactions is discussed.
