%X 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.
