Electric field control of spin orbit coupling and circular photogalvanic effect in a true ferrielectric crystal.

ABSTRACT: Materials possessing long-range ordering of magnetic spins or electric dipoles have been the focus of condensed matter research. Among them, ferri-systems with two sublattices of unequal/non-collinear spins or electric dipoles are expected to combine the properties of ferro- and antiferro-systems, but lack experimental observations in single-phase materials. This is particularly true for the ferrielectric system, since the electric dipoles can usually be redefined to incorporate the two sublattices into one, making it indistinguishable from ferroelectric. This raises doubts about whether or not ferrielectricity can be considered as an independent ferroic order. Here we report the observation of true ferrielectric behaviors in a hybrid single crystal (MV)[SbBr₅] (MV²⁺
