Spin dynamics in molecular multiferroic (ND4)2[FeCl5(D2O)]

ORAL

Abstract

(ND4)2[FeCl5(D2O)] is a molecular magnet that exhibits extraordinary coupled magnetic and ferroelectric properties. Applying modest magnetic field induces successive magnetic transitions with distinct magnetoelectric (ME) coupling and the underlying mechanism is not fully understood yet. Knowing the microscopic interactions is essential to understand the complex coupled phenomena. We performed inelastic neutron scattering experiments to measure the spin dynamics in (ND4)2[FeCl5(D2O)]. We will present here some INS data analysis results using linear spin wave theory.
