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 10kHz. Although it can do measurements on powder samples, single crystals are preferred.

Varian EPR

This old but reliable instrument is the workhorse for our EPR measurements. It is equipped with a 1.3 Tesla magnet and is used for Q-band (35 GHz) and X-band (9.5 GHz) EPR. The samples can be cooled down to liquid nitrogen temperatures.

Hewlett-Packard UV-Vis

A modern Windows-based UV-vis capable of all the standard applications of these instruments. This instrument is used to obtain indications of the electronic properties of transition metal complexes.

TA Instruments MDSC

This top-of-the-line DSC is capable or running both modulated and standard DSC experiments over a temperature range of -180 C to 725 C. We are able to obtain heat capacity and transition temperatures for phase changes of various compounds.

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.

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 N2 and He cryostats.
