8400 Series HMS

Technical Specifications

Ideal for variable temperature measurement and mobilities from 1 to 106 cm2/V ‍s

Optional AC field extends mobility measurement range down to 10-3 cm2/V ‍s

Maximum DC fields to 1.67 T (8404) and 2.25 T (8407)

Optional AC fields to 1.18 T (8404) and 1.31 T (8407)

Standard resistance range of 0.5 mΩ to 10 MΩ

High resistance option widens range to 200 GΩ

Low resistance option significantly reduces resistance noise floor

Temperatures from 15 K to 1273 K

Also available as an option for the CRX-VF cryogenic probe station

2 in pole caps not recommended for use with variable temperature in the 8407

*Field specification assumes the high-uniformity option is used with variable temperature to get a 2:1 ratio of pole cap face to air gap, which is preferred for operation at large gaps. Specifications are subject to change.

Featuring patented* FastHall technology, the M91 fundamentally changes Hall effect characterization by eliminating applied magnetic field polarity switching. This results in faster, more accurate measurements, especially with high-field superconducting magnets or low-mobility materials.

The Lake Shore 8400 Series can be used with both DC and AC field Hall measurement methodologies to facilitate the broadest range of research applications. The system includes fully integrated instrumentation, a magnet and power supply, plus software that dramatically helps you increase your research productivity and provides results that you can trust.

When used with the AC field measurement option, the system is ideal for use with the emerging class of materials that typically have mobilities below 1 cm2/V ‍s—the types of materials with electronic properties that can be difficult or impossible to measure with traditional DC field Hall methods. These include many contemporary semiconductor and electronic materials, such as photovoltaic (solar cell) and thermoelectric materials, new display technologies, and organic electronics.
