Magneto-Raman Spectroscopy on multiferroic metal-organic framework [(CH3)2NH2]Co(HCOO)3

ORAL

Abstract

Metal-organic frameworks (MOFs) are a class of nanoporous compounds where organic groups are used in combination with transition metal ions to obtain multifunctional materials. The family of MOFs perovskites ABX3 comprised of methylammonum (A= (CH3)2NH2) and metal (B=Co, Cu, Fe, Mn, Ni) cations with a formate (X=HCOO3) anion are studied because of their multiferroic properties [1]. Therefore, several efforts have been made to understand the nature and strength of exchange interactions in these materials including magnetization at high magnetic fields up to 60 T and infrared spectroscopy at magnetic fields up to 35 T [2,3]. Concurrently, we performed magneto-Raman spectroscopy on [(CH3)2NH2]Co(HCOO)3 at magnetic fields up to 31T to probe the magneto-elastic coupling, the results of our investigations and its implications will be discussed.
