Miniature capacitive Faraday force magnetometer for magnetization measurements at low temperatures and high magnetic fields.

A Faraday force magnetometer is presented for measurements of magnetization at temperatures down to 100 mK and in magnetic fields up to 14 T. The specimen is mounted on a flexible cantilever forming a force-sensing capacitor in combination with a fixed back plate. Two different cantilever designs are presented. A torsion resistant cantilever allows us to measure the magnetization of highly anisotropic single crystal samples. Measurements of the metal organic quantum magnets (C
