The single stage variable temperature assembly allows
you to take measurements from 100 K to 1000 K
using nitrogen, LN2, and argon gas. A single point
measurement can be taken at 78 K. Only one hardware
device is required to go from high to low temperatures,
eliminating the need to remove or resaddle your sample.
This ensures accurate measurements throughout the full
scale temperature range. Rapid cool down from 1000 K
to room temperature and from room temperature to
100 K provides efficiency and high throughput. Like our
full suite of variable temperature options, the single
stage variable temperature assembly is mechanically
isolated from the magnetometer head and sample,
minimizing noise floor. Designed to deliver superior
thermal performance, the unit’s vacuum insulation
prevents freeze over at low temperatures and can
operate safely at high temperatures without the risk of
damaging neighboring components. |

The MR probe option performs fast and accurate
measure-ments of MR, GMR spin-valve, CMR and other
magneto-resistive materials as a function of both in-plane
magnetic field and temperature. This measurement option
includes data acquisition, control, and analysis software to
automatically extract pertinent parameters for the device
under test. These include free and pinned layer parameters
of both simple and synthetic
spin-valve sensors.
The MR probe features four
in-line pins for solder-less
connection to the sample
and is interchangeable with
the VSM sample rod for
compatibility with variable
temperature and autorotation
options. The temperature
range of use extends from 20 K
to 450 K when used with the
74018 LHe/LN2 cryostat, 325 K
to 675 K with the 74034 oven,
and 100 K to 675 K with the
74035 single-stage variable
temperature assembly. Angular
dependent MR measurements
are possible when used in
combination with the 74033 autorotation option. Contact
pins maintain their position on the sample while the entire
assembly rotates with respect to the magnet field. |
