Abstract

By measuring the electric field dependence of EPR spectra of the ferroelectric liquid crystalline (FLC) phase of (2S,5S)-1 confined in a surface-stabilized liquid-crystal cell, two magnetic bistable states were observed. These states occur because of the anisotropy in spin–spin dipole interactions responsible for positive ‘magneto-LC effects’, which refer to the generation of a sort of spin glass-like ferromagnetic interactions (average spin–spin exchange interaction constant [J with combining macron] > 0) induced by weak magnetic fields in the various liquid crystalline (LC) phases of nitroxide radical compound 1.
