Abstract: PROBLEM TO BE SOLVED: To provide a magnetooptic effect measurement device capable of heating a micro region on a sample and carrying out temperature measurement and magnetic measurement of the region accompanying the heating.SOLUTION: The magnetooptic effect measurement device generates a first light beam given characteristics of linear polarization and circular polarization in a magnetic measurement mode, and generates a second light beam having an infrared wavelength in a temperature measurement mode. A direct incidence type reflecting optical element converges the second light beam on a micro region on a magnetic sample to heat the region, and infrared rays radiated from the micro region as the micro region is heated are propagated by the direct incidence type reflecting optical element to measure temperature. While a magnetic field is applied to the magnetic sample, the first light beam is converged by the direct incidence type reflecting optical element to irradiate the micro region, subjected to action of magnetooptic effect in the micro region, and propagated.
