The optical Faraday effect hysteresigraph is an instrument for measuring the static thermomagneto-optic properties of thin transparent magnetic film samples. Via an oscilloscope, it displays 60 Hz magnetic hysteresis loops of the samples over a temperature range of 20°C±40°, with peak magnetic fields of 2600 Oe. Its use of thermoelectric elements results in a compact package, highly effective for rapid change and accurate control of sample temperature.
