Study of the lattice and spin dynamics in the Metal-Organic Framework (CH3NH3)Co(COOH)3
Magnetic hybrid organic-inorganic Perovskites have attracted much attention lately as they potentially show a magneto-electric coupling, thanks to the strong interaction between the framework and the molecular host. In particular, a diffraction study at zero-field of CH3NH3Co(COOH)3 shows a structural transition around 90 K concomitant with an antiferroelectric behaviour and a magnetic order below 15 K. Under applied field, magnetisation and polarisation measurements highlight a coupling between the magnetic and electric order. We would like to investigate the lattice and spin dynamics at zero-field in this system, in order to better understand the interplay between the magnetic framework and the molecular host, which leads to these field-induced properties. We hence request 8 days on IN12.
