Magnetic Properties Measurement System (MPMS)

MPMS is a very sensitive magnetometer due to the utilization of a liquid Helium cooled SQUID (superconducting quantum interference device) to measure changes in the magnetic flux, which is converted to and measured as current, as the sample moves through the superconducting detection coil.

Our Quantum Design MPMS makes it possible to study the magnetic properties of materials at temperatures from 1.8 to 400 K under magnetic fields of up to 7 Tesla. For measurements up to 800 K, a sample space oven has been implemented. It is possible to measure materials in powder, single-crystal or pellet form.

Fig 2. A typical MPMS measurement in our lab: Temperature dependence of the magnetization of both polycrystalline (PX) and single-crystal (SX) YVO3 under an applied magnetic field of 1 kOe. Filled and open circles are for the PX samples after field-cooling (FC) and zero-field-cooling (ZFC), respectively. The data for single crystal are obtained by averaging the magnetizations along the three axes.From Y. Ren et al. Phys. Rev. B62, 6577 (2000)
