Lake Shore presenting at EMC conference on improved AC field Hall measurements
EMC 65

Lake Shore Cryotronics will present “Improved AC Field Hall Measurements Using Hybrid Filters” at this week’s Electronic Material Conference at the University of California-Santa Barbara, where the company will also be exhibiting.

In his 2:50 p.m. Wednesday talk, Applications Scientist IV Jeff Lindemuth will describe how a combination of digital lock-in output stage filters, utilizing FIR and IIR low-pass filters, can produce improved noise reduction and measurement time over the traditional approach of using independent IIR filters or FIR filters for Hall effect measurements of electronic materials.

The presentation is based on the work of Lindemuth and Lake Shore applications scientists David Daughton and Emilio Codecido and involves the use of a Lake Shore MeasureReady™ M81-SSM source measure system used in conjunction with a 7-inch 1.31 T electromagnet and magnet power supply. The all-in-one M81-SSM system provides highly synchronized DC, 100 kHz AC, and mixed DC + AC sourcing and measuring — including both voltage and current lock-in measurement capabilities — for researchers exploring the electrical properties of new materials.

For those who want to learn more about the M81-SSM, Lindemuth, along with Lake Shore’s Kevin Carmichael, will be available in the exhibit area to show a demo of the system, set up to demonstrate measurements using the system’s BCS-10 balanced current source and VM-10 voltage source modules.

The M81-SSM can also be ordered as part of the new CryoComplete™ system, which includes everything needed to start taking temperature-dependent (77 K to 500 K) electrical measurements out of the box, including an Environment by Janis LN2 cryostat, temperature controller, and PC with MeasureLINK™ control software.

In addition to the M81-SSM, Lake Shore will also be answering questions about:
