METHOD measuring the magnetic moment of the sample A SQUID magnetometer

摘要

A method of measuring the magnetic moment of the samples with a SQUID magnetometer comprising a mechanical sample movement, characterized in that before measurement the sample is placed at a distance from the receiving coil at the top, at the output of the magnetometer is set a zero voltage, then the sample is moved down to a position slightly below the upper receiving coil, wherein the record maximum value Uvyhodnogo voltage magnetometer on the basis of which determine the magnetic moment M of the sample formuleM = k · U-M, where k - calibration intercept NTA, M contribution from the sample holder.
