High-frequency oscillator magnetometry measurement in the pulsed magnetic field

Recently, the clear quantum oscillations have been observed in an unusual high-field metallic state of the Kondo insulator YbB₁₂, probed by the proximity detector oscillator which was used for the contactless shubnikov-de Haas (SdH) effect studies. However, the de Haas-van Alphen (dHvA) effect has been barely studied in the pulsed magnetic field because of the eddy current present in the metal cantilevers. High-frequency quartz oscillators can be a solution to probe the dHvA effect in the pulse field. Therefore, we developed a torque differential magnetometry technique based on high-frequency oscillators. In this presentation we report on our progress on the torque carry on the measurement in YbB₁₂.
