Magnet, Low Temperature, and Optical Facility

This facility maintains various magnet, cryogenic and optical systems operating either separately or together. The systems are designed to be as flexible as possible, and to allow several types of measurements to be performed over a wide range in magnetic field, temperature, and probe frequencies (including both uhf/microwave and optical). The dc and uhf/microwave frequency measurements that are routinely performed include magnetization and magnetic susceptibility, acoustic propagation, microwave absorption, electrical transport (including thermoelectric measurements). Routine optical measurements include optical absorption, photoluminescence, pump-probe studies, and Raman spectroscopy. 

Facility Type: 


  1. Andor 303 mm focal length Czerny-Turner spectrograph
  2. Computer-controlled Quantum Design Physical Properties Measurement System (PPMS)

    The PPMS was designed to measure heat capacity, thermal transport, and thermoelectric effects.  Key optional features of the MPMS have been greatly expanded and improved in the PPMS.  The PPMS brings a new level of measurement automation to researchers in rapidly expanding fields such as materials science, condensed matter physics, biology and analytical chemistry.

  3. DU420A-BEX2-DD thermoelectric cooled camera
  4. EKSPLA PL2143SS

    EKSPLA PL2143SS 30 picosecond pulsed neodymium-doped yttrium aluminum  garnet (ND:YAG) 1064 nm laser with doubler (532 nm), trippler (355 nm), and OPA.

  5. Lakeshore AC susceptometer

    capable of measuring both real and imaginary components of susceptibility

  6. Quantum Design Magnetometer (MPMS5)

    The MPMS provides the exceptional sensitivity of a SQUID-based magnetometer in a fully automated, analytical instrument. It provides a much needed solution for a unique class of magnetic measurements, meeting the needs of research in key areas such as high-temperature superconductivity, biochemistry, and magnetic recording media. This system was upgraded in 2004 by the addition of a horizontal rotator option and an "oven" insert for high-temperature measurements. This instrument can measure DC magnetic susceptibility and magnetic moments on samples as small as a few mg.
