Lake Shore’s all-in-one instrument offers complete Hall measurement and analysis

Lake Shore Cryotronics Inc of Westerville, near Columbus, OH, USA (which makes scientific sensors, instruments and systems for measurement and control under low-temperature and magnetic field conditions) claims that, for researchers studying semiconductor materials, its new MeasureReady M91 FastHall measurement controller delivers significantly higher levels of accuracy, speed and convenience compared with traditional Hall-effect measurement solutions.

Combining all the necessary Hall measurement system functions into a single instrument, the M91 automatically executes measurements, collecting the data and calculating the final Hall and mobility parameters, outputting ‘answers’ not just data. By automatically optimizing the excitation and measurement range, the instrument eliminates manual trial-and-error steps and ensures that measurements are always made under optimal conditions for the sample.

The instrument is said to also provide better measurements faster – especially with low-mobility materials. Most commonly measured materials can be analyzed in a few seconds. Its speed is due mainly to Lake Shore’s patented FastHall technology, which eliminates the need to reverse the magnetic field during the measurement. This is particularly beneficial when using superconducting magnets, which are relatively slow at completing field reversals.

The firm also says that the M91 is easy to use, can be integrated easily with existing lab systems, and provides a cost-effective way for researchers to build a new Hall system or upgrade an existing one.
