Spin Phonon Transition

Measurements at X-band frequencies of relaxation times and spin–phonon transition probabilities in ruby grown by the "vapor phase" method were carried out. They demonstrate the existence of relaxation processes which cannot be related to the spin–lattice coupling parameters obtained from ultrasonic and static stress experiments.

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.
