Abstract
Liquid crystals (LCs) are typical soft materials that possess both mobility and ordered self- assembled structures. Incorporation of paramagnetism into chiral rod-like LCs is expected to result in the emergence of unique magnetic interactions, magneto-optical or magneto-electric properties, and so on in the LC state. In order to shed light on the relationship between electric-dipole and magnetic-dipole moments, we measured the electric field dependence of paramagnetic susceptibility in the ferroelectric (SmC*) state of 1 by EPR spectroscopy. Consequently, a hysteresis loop was observed. This result suggests that the magnetization in the SmC* state is affected by applied electric fields owing to the occurrence of magneto-electric effects.
