Magnetic Measurement under High Pressure Using Superconducting Quantum Interference Device

Abstract

In this article, recent advances in the magnetic measurements under high pressures of above 10 GPa using superconducting quantum interference device (SQUID) were reviewed. SQUID is a magnetic device with high sensitivity, while it has a problem of drift in output voltage such that the offset mechanism should work to pick up a signal of targeted material. We review the experimental approaches using two types of apparatus; (1) sample transport method and AC magnetic field method by using a commercial SQUID magnetometer and (2) vibrating coil method by using a hand-made SQUID magnetometer.
