AC·Magnetisation

Measurement frequency range 10 Hz to 10 kHz; AC magnetic moment resolution, 2-8 emu @10 kHz; 5-point / 3-point metering for high-precision AC magnetisation measurement;

Multifield Technology· customised piezoelectric shield, “Motion + Detection” at the same time in a low-temperature and strong magnetic environment;；

Because the measurement algorithm requires the sample to be moved three/five times during the measurement process, Multifield Technology has placed the power module directly into a cryogenic environment, rather than the traditional solution of placing the electromagnetic motor at room temperature and carrying the sample through the chamber by means of a 1m-long sample rod.

1. Extremely compact design, supporting sample chamber cryogenic systems by means of a “sample rod”; also supports systems without sample chamber, with direct mounting of the cryogenic end;

Core Measurement Module- Tolerance within 15cm, OD within 25mm;

2. Supports expansion to 300 mK and dilution chiller environments;

The sample position is fixed and the piezoelectric motor moves the “drive/detection-coil set” by 3 – 4 cm;

Relative movement of the sample in the probe coil is achieved by using a piezoelectric motor to drive the coil pack while the sample remains motionless;

1. The position of the sample remains unchanged to ensure that it is always at the centre of the magnetic field;

With a third-party low-temperature magnetic field platform, highly accurate measurements can be obtained even in narrow magnetic uniformity zones (e.g., 1cm);

2. No He gas thermal conductivity is required, and the sample temperature is equally stable even in high vacuum environments;
