Spin-Phonon coupling in Y${}_2$NiMnO${}_6$ double perovskite probed by Raman spectroscopy

Abstract

We performed Raman spectroscopy measurements under temperature changes from 10 K up to 850 K to probe the phonon-spin coupling in Y${}_2$NiMnO${}_6$. The spin-phonon coupling was observed as a softening of the stretching mode, indicating this phonon stabilizes the magnetic interaction. The result indicates the rare earth ionic radius in Re${}_2$NiMnO${}_6$ double perovskites is not the unique parameter influencing the spin-coupling magnitude.
