Abstract

An all-electrical torque differential magnetometry (also known as cantilevermagnetometry) setup employing piezoelectric quartz tuning forks is demonstrated. Themagnetometer can be operated under ambient conditions as well as low temperatures andpressures. It extends the allowed specimen mass range up to several 10 μg without any significantreduction in the sensitivity. Operation under ambient conditions and a simpleall-electrical design of the magnetometer should allow for an easy integration with otherexperimental setups. The uniaxial magnetic anisotropy of a 25 μm diameter iron wire,measured under ambient conditions with a high signal to noise ratio, was found to be ingood agreement with its literature value. Further applications of the technique arediscussed.
