摘要：

this study proposes a method for the calibration of vibrating sample magnetometer (VSM), designed to compensate for the effects of internal demagnetizing field. This method utilizes finite element calculations and evolutionary search to find the optimal demagnetizing factor. This method has been validated to exhibit higher accuracy than existing methods, and the calibrated magnetic property aligns well with the results obtained through the capacitive cancellation method.
