The AC Susceptometer option uses a small primary excitation coil to apply an AC field to a sample (typically 1mT at frequencies from 0.1 Hz 10000 Hz). A pair of secondary pick-up coils positioned close to the excitation coils are used to detect the sample response. The resultant signal is measured using a Lock-In amplifier with the in-phase and out-of-phase components of the signal corresponding to the real and imaginary components of the AC Susceptibility of the sample. An additional compensation coil is used to eliminate background signals.

S700X -
Cryogenic Ltd.
The S700X SQUID Magnetometer is the most sensitive instrument for DC and AC measurement of magnetic properties as a function of magnetic field and temperature. Numerous different experiments may be performed with this unique instrument. The SQUID sensor at the heart of the system has an input noise power sensitivity of approximately 10-30 Joules per root Hz. This energy sensitivity is 108 better than any semiconductor device and accounts for the instrument's ability to resolve extremely small magnetic signals with accuracy and speed. The S700X has several modes of operation. The most widely used is the measurement of total magnetic moment made by moving the sample through a set of pick-up coils. During the measurement the sample temperature and applied magnetic field are precisely controlled. The second order gradiometer configuration used for the pick-up coils is insensitive to the externally applied field but allows samples of 10-11 Am2 total moment to be resolved with ease.

Cryogenic uses various cryocoolers with cooling powers to suit different cryogen free magnet systems and applications. The Gifford-McMahon cycle cryocooler has the advantage of greater thermodynamic efficiency. The pulse-tube cryocooler is vibrationally quieter, has a longer service interval and cools faster from room temperature.

The Resistivity System allows the user to make Resistivity and Hall Effect measurements in the range of to M. Samples are mounted on special platforms inside the VTI with contacts made to the sample according to the customer's requirements. Connections at the top of the probe are made via Fischer Connectors or Coaxial Cables. Keithley source and measurement electronics are provided with the system. These are fully controlled using the Measurement System Software.

EPR -
Cryogenic Ltd.
EPR samples with S=1/2 electronic spins exhibiting a narrow signal at G=2 and require magnetic fields of only ca. 3.5 T. However, EPR spectra from S>1/2 spins are typically much broader and have spectral features that spread over magnetic field range of several Tesla. Such fields could be easily achieved with superconducting magnets, but, unlike NMR, these magnets cannot operate in a persistent mode in order to satisfy a wide range of resonant fields required by the experiment.
