-The magnetic infrared sensor (MIS) is a detector utilizing the pyromagnetic effect of ferrimagnetic film (FMF) with a low Curie temperature. When infrared rays are absorbed by the MIS, there is a magnetization change in the sensor. This change is read out by a magnetoresistunce element and is converted into si voltage with a peak value that increases with a rise in infrared energy. This paper describes the construction of the MIS, and characterization to infrared rays.
