Lake Shore Cryotronics will be discussing their industry-leading vibrating sample and alternating gradient magnetometers (VSMs/AGMs) and cryogenic probe stations at the XXIV International Materials Research Congress (IMRC), August 16 – 20, in Cancun, Mexico.
In Booth T7, Lake Shore Senior Scientist Brad Dodrill will answer questions about the company’s high-sensitivity VSMs/AGMs, which enable researchers to accurately and quickly characterize magnetic properties of materials over a 4.2 K to 1,273 K temperature range and in magnetic fields to >3 T.
VSMs/AGMs are ideal for many applications, including research into magnetic thin films, multi-layers, nanomagnetic materials, and magneto-caloric effect (MCE) materials. They also provide valuable insights when studying permanent magnets, including rare earth materials, as well as natural magnets (rocks, sediments, etc.), amorphous magnets, ferrofluids, and diluted magnetic semiconductors.
During the congress, at the 4 p.m. Monday 7E Phase Transitions in Magnetic Materials Symposium, Dodrill will present an invited talk on “First-Order-Reversal-Curve Analysis of Magnetic Materials.” FORC measurements are crucial in understanding magnetic properties and in determining the distribution of switching and interaction fields in many magnetic materials. Lake Shore MicroMag™ VSM/AGMs are arguably the standard for FORC measurements because of their measurement speed.
Also at the congress, Dodrill will also be discussing the company’s line of micro-manipulated, high-vacuum probe stations for on-wafer probing and measurement of materials. These platforms enable electrical, electro-optical, DC, RF, and microwave measurements of material and device properties at cryogenic temperatures (as low as 1.6 K) and under the application of high magnetic field.
A number of probe station versions and options are available from Lake Shore, including an upcoming THz-frequency contact probing arm option for cryogenic applications. This unique option will enable precise on-wafer probing of millimeter wave devices and materials at frequencies above 75 GHz.
Lake Shore will provide information on their:
- Advanced Hall effect systems, including its 8400 Series HMS with an AC field Hall measurement option for characterizing materials with very low mobilities down to 0.001 cm2/V s.
- Fully integrated Model 8501 THz system for non-contact characterization of research-scale materials, which features a high-field cryostat, enabling measurement of material spectroscopic responses across a wide range of frequencies, temperatures, and field strengths.
- Sensors and instruments for stable, reliable low-temperature measurements.
