Quantum Design PPMS

 

This state-of-the-art Physical Property Measurement System is used for obtaining AC and DC magnetization, heat capacity, transport properties, and W-band EPR (95 GHz) measurements on the compounds synthesized in this (and collaborating) labs. It operates down to 1.8K and is equipped with a superconducting magnet capable of fields up to 90,000 Gauss. The AC frequencies can be varied from 10 Hz to 10 kHz. Although it can do measurements on powder samples, single crystals are preferred.

Bruker Elexsys-500 EPR

 

This is a state-of-the-art continuous wave (CW) EPR spectrometer with both X-band (9.5 GHz) and Q-band (34 GHz) microwave bridges. The X-band is equipped with a high-Q cavity, computerized goniometer, liquid N2, and liquid He cryostats (allowing us to probe temperatures down to 2 K). The Q-band features a standard TE 011 cavity for CW measurements along with Liquid Nitrogen and Helium cryostats.

Quantum Design MPMS XL-7 Magnetometer

 

This is an extremely sensitive mutual inductance type magnetometer utilizing SQUID electronics to detect very small changes of magnetic flux within the inductance coils. This instrument is extremely sensitive to small samples such as single crystals. We also have the capability to study the effects of light on magnetic samples using a fiber optic sample holder and a variable wavelength lamp.

NMR in Dr. Reyes' Lab at the National High Magnetic Field Laboratory

 

This high field NMR (17.5 T) is capable of conducting very sensitive measurements at temperatures down to millikelvin with the use of liquid helium-3.
