• # Abstract

Resonance width, shift in resonance frequency, relaxation time and activation energy of 5CB nematic liquid crystal are measured using microwave cavity technique under the inﬂuence of an external magnetic ﬁeld at 9 GHz and at different temperatures. The dielectric response in liquid crystal at different temperatures and the effects of applied magnetic ﬁeld on transition temperatures are studied in the present work. The technique needs a small quantity (&lt; 0.001 cm3) of the sample and provides fruitful information about the macroscopic structure of the liquid crystal.
