Magnetic Order Through Super-Superexchanges in the Polar Magnetoelectric Organic-Inorganic Hybrid Cr [(D3N-(CH2) 2-PO3)(Cl)(D2O)]

Résumé

Partially deuterated Cr[D3N-(CH2)2-PO3)(Cl)(D2O)] has been studied by neutron powder diffraction and magnetization measurements down to 2 K. The precise crystal structure of the compound was determined. The strong magnetodielectric coupling reported and weak ferromagnetic component can be explained by the determined magnetic structure. The transition from paramagnetic to weakly ferromagnetic state results from super-superexchanges only and has been explained by theoretical analysis based on first-principles DFT calculations.
