Lake Shore JEMS exhibit to feature magnetic material characterization systems

Lake Shore Cryotronics will be at next week’s Joint European Magnetics Symposium (JEMS) in Glasgow, U.K., to discuss their comprehensive line of magnetic materials characterization systems and other magnetic measurement solutions.

At Stand 2, Lake Shore representatives will be on hand to answer questions about the new 7400-S Series VSM, which combines high sensitivity, precision electronics, and flexible application software with the ability to characterize material properties as a function of temperature.

This high-performance magnetometer system offers fields to over 3.4 T and a 4.2 K to 1273 K temperature span for characterizing a broad range of magnetic material samples. These include magnetic thin films; nanomagnetic composites, dots, wires, arrays, and molecular materials; magnetic multi-layers and hetero-structures for spintronics (GMR, TMR); diluted magnetic semiconductors; superconductors; ferrite and rare-earth permanent magnet materials; and geomagnetic samples.

Users can execute measurements quickly using the 7400-S software’s Windows® interface, with any number of parameters automatically extracted from hysteresis loop data when measuring material samples in powder, solid, liquid, or thin film form. Also available are free 7400-S software utilities for first order reversal curve (FORC) data acquisition and characterizing magnetocaloric effect (MCE) behavior of materials.

Backed and supported by more than 40 years of expertise in measurement technologies, Lake Shore offers on-site operational training and verification for their VSMs and other material characterization systems, magnetic sample measurements for customers early in the VSM evaluation and system configuration process, and extensive post-sale technical support.

Dr. Cosmin Radu, Lake Shore Application Scientist, will be available at JEMS to answer customer questions about Lake Shore systems and instruments as they relate to their research applications and the types of materials they aim to characterize. Dr. Radu has extensive experience with a number of magnetometer techniques (VSM, SQUID, AGM, etc.), and as a scientist has published research relating to the magnetic properties of nanostructured materials and novel investigation techniques.

Also at JEMS, Lake Shore representatives will discuss:

  • Precision gaussmeters, fluxmeters, Hall probes, and Helmholtz and search coils; in addition to manufacturing test/QC applications, gaussmeters and Hall probes are used in research labs to compare the magnetic fields of various materials and explore magnetic phenomena.
  • Cryogenic probe stations with integrated in-plane and out-of-plane magnets for DC, RF, microwave, and THz-frequency probing of materials in a tightly controlled, variable-temperature environment. The stations are for early-phase material research when it is often necessary to measure samples at temperatures below 4 K and in fields to more than 2 T.
  • Their 8500 Series THz material characterization system for non-contact characterization of research-scale materials; this fully integrated system features a high-field cryostat enabling material spectroscopic response measurements across a wide range of frequencies, temperatures, and field strengths.
  • Hall effect measurement systems for performing Hall effect and magnetotransport measurements on materials, including wafer-scale materials, as a function of temperature and field.
