An application of magnetic Compton scattering as a new tool to measure a spin‐specific magnetic hysteresis (SSMH) loop is introduced and its validity demonstrated. The applied magnetic field dependence of the integrated intensity of magnetic Compton scattering spectra, which reflect only the spin‐dependent magnetic properties of magnetically active electrons, was interpreted as the spin‐specific hysteresis. The spin magnetization of amorphous Tb 33 Co 67 film was observed and its SSMH loop exhibited qualitative agreement with the ordinal magnetic hysteresis loop measured using a conventional vibrating sample magnetometer.
