VIBRATING SAMPLE MAGNETOMETER
(VSM)
The VSM measures the magnet
moment by moving the sample between two pick-up coils at
frequency of 1 to 100Hz. Sensitivity is to 10-6 emu with a suitable averaging time.
The standard temperature range is 1.6K
to 325K with fields up to 18 Tesla. A Helium-3
option is available which allows tempratures down to 300mK
for some type of measurements.
Cryogenic offers the
VSM measurement capability in two options:
Option 1: Fully
integrated Cryogen Free VSM measurement System to
18 Tesla.
The VSM measures the magnet
moment by moving the sample between two pick-up coils at
frequency of 1 to 100Hz. Sensitivity is to 10-6
emu with a suitable averaing
time. The standard temperature range is 1.6K to 325K
with fields up to 16 Tesla. A Helium-3 option is
available which allows tempraturesdown to 300mK for some type
of
measurements.
The pick-up coils are built
into the main magnet system . These have the
advantage that the coils are at 4K independent of the
sample temperature but require a larger magnet with a
smaller
VTI.
The system would include Helium Free
or liquid helium Cryomagnet, Variable
Temperature Sample space, a set of special probes which
carry the sample, as well all the electronics, computer
and measurement
software.
Option 2:
Cryogen Free Mini VSM Measurement System.
Cryogenic offers the Mini helium free magnet
system with fields up to 5 Tesla for measurements of
Electrical, Magnetic and thermal properties of material.
The mini measurement system is built around a
modular framework with a cryogen free platform. The
system consists of a cryogen free magnet (up to 5
Tesla), Variable temperature Insert, two cryocoolers
(pulse tube and GM), special probes to measure different
material properties, computer, electronics and
measurement software.
The system is delivered as an integrated turnkey
system with installation, training and support.
