✦ Synopsis

Raman and IR studies of a single orthorhombic crystal and of polycrystalline trigonal RbIn(MoO 4 ) 2 were performed at ambient temperature. The observed vibrational modes were assigned to the respective motions of atoms in the unit cells. It was shown that the first-order D 3d 3 β†’ D 2h 16 phase transition leads to very significant changes in the vibrational properties of the crystal studied.

We appreciate the comments of Man ˜osa et al. on our recently published paper, [1] which reported a method to properly evaluate the magnetocaloric effect (MCE) in the vicinity of a first-order phase transition and reveal the puzzled origin of spike-like entropy change for the LaFe 11.
