The invention provides a method for measuring the magnetic moment of a transition metal material based on XPS, and the method comprises the steps: selecting a to-be-tested material single crystal, and transferring a single crystal sample into an X-ray photoelectron spectrometer; selecting an X-ray source; setting a test point position, and setting scanning parameters including energy passing, scanning step length, beam spot size and a magnetic lens mode; selecting a peak value of a 2p orbit high-resolution narrow spectrum corresponding to the transition metal contained in the to-be-detected sample as a fixed-height reference signal, and etching the surface of the sample to remove surface pollution; determining the position of a 3s orbit characteristic peak according to a broad spectrum, and collecting a 3s orbit high-resolution narrow spectrum of transition metal contained in the sample; collecting a valence band spectrum or a C1s orbit high-resolution narrow spectrum for correcting a broad spectrum and a 3s orbit high-resolution narrow spectrum; correcting the binding energy by adopting a correction reference, carrying out peak-dividing fitting through XPS peak-dividing fitting software, and extracting characteristic parameters of a 3s orbit spin exchange split peak; and calculating to obtain the magnetic moment of the transition metal material.
