1.2 Specifications

The Model 74046 magnetoresistance insert probe option for the 7400 Series VSM
provides a method to measure magnetoresistance (MR) effects with a small sample
geometry. Magnetoresistance can be measured both at room temperature and at
variable temperatures when placed within the sample bore of a Lake Shore VSM
temperature appliance such as a Model 74034 oven or Model 74018 cryostat. The
MR insert itself works in conjunction with a Keithley Model 2400 current source,
Lake Shore Model 775 matrix switch, Lake Shore Model 736 VSM controller and
Lake Shore electromagnet and power supply to comprise a versatile MR sample test
system.
