Building a Faraday Force Magnetometer for Magnetization Measurements of Quantum Materials at 50mk Under High Magnetic Fields

ORAL

Abstract

The purpose of this presentation is to discuss the fabrication and experimental setup of a previously designed Faraday Force Magnetometer used for magnetization measurements of Quantum Materials. New design updates have been implememtned on this probe, measuring 20mm x 20mm x 15mm, and measurements have been completed validating previously claimed sensitivity resolutions. This probe, placed in a dilution refrigerator and cooled to 50mk, can test magnetization of materials up to fields of 14T with a resolution better than 10^−4 emu. By the time of this presentation we hope to present new measurements of CeCl3 and other samples with a nominal sensitivity of 10^-6 emu. We will discuss limitation of sensitivity and challenges in practical implications at ultra low temperatures.
