Phase transitions that produce small length changes (even on the order of nanometers) due to thermal expansion or magnetostriction can be resolved by making contact between the tip of a miniature piezo-resistive cantilever and a sample.
Specific heat of a material is a measure of heat necessary to raise the temperature of a given amount of material, typically a gram or a mol, by 1 Kelvin.
High currents measurements in the MagLab are used mainly for characterization/testing of superconducting materials.
A vibrating sample magnetometer (VSM) is used to measure DC magnetic susceptibility and DC magnetization. The VSM utilizes the Faraday’s Law to measure absolute magnetic moment of a magnetic sample.
Dielectric capacitance measures capacitance and dissipation of a bulk or thin film sample.
Bruker FTIR spectrometers are coupled to SCM3 and resistive magnet in cell 8.
In a Raman scattering experiment, a specimen is shined with laser light of a known frequency (energy) and polarization, and the scattered light is collected and analyzed for frequency and polarization.
This technique utilizes a streak camera in order to measure photoluminescence lifetimes with a minimum duration of 2 ps.
The Magneto-optical Kerr probe provides the laboratory with a unique apparatus to measure properties of ultra-thin magnetic films and multilayers at high magnetic fields and cryogenic temperatures (2K-325K).
Wideband microwave measurement capacity to 40 GHz.
