Abstract
One issue with the micro-superconducting quantum interference device (micro-SQUID)magnetometer system is the magnetic flux detected by the SQUID loop cannot be converted tosample magnetization. Herein we present a technique for absolute quantification ofmagnetization of a microcrystal sample using a micro-SQUID magnetometer. The fielddependence of the magnetic flux from a microcrystal of a known molecular ferromagnet,RbMn[Fe(CN)6], was measured. Then, by combining the experimental data and a simple dipoleapproximation calculation, a highly accurate molar effective magnetic moment wasobtained.
