Magneto-Optical Effects in Temperature-Sensitive Ferrofluids

Abstract

A temperature-dependent magneto-optical study of three different temperature-sensitive fluids was carried out. The changes in transmitted intensity as a function of applied magnetic field and temperature are recorded. The study provides an alternative technique for determining the Curie temperature of such fluids, and it is also feasible for the monitoring of temperature changes of such fluids optically within a limited time span.
