New magneto-optic effect on the spectral thermal infrared emission from ferromagnets

Abstract

IN 1977 MUELLER, FUCHS AND KNEUBUEHL DISCOVFRED THE PARTIAL CIRCULAR POLARIZATION OF THE SPECTRAL THERMAL EMISSION FROM AXIALLY MAGNETIZED FERROMAGNETS. NOW, WE HAVE ORSERBED A RELATED EFFECT, THE PARTIALLY LINEAR POLARIZATION OF THE EMISSION FROM IRON MAGNETIZED TO ITS SURFACE. WHILE THE PARTIAL CIRCULAR POLARIZATION IP PROPORTIONAL. TO THE MAGNETIZATION. THE PARTIAL LINEAR POLARIZATION SHOWS A QUADRATIC DEPENDENCE IN A FIRST APPROXIMATION.
