GMW is a Sponsor at Intermag’21 Virtual Conference April 26-30, 2021

GMW is a sponsor of the 12th MRAM Global Innovation Forum and the Best Poster Award. Continuing developments from GMW include:

  • Benchtop High Uniformity Electromagnets. These Magnet Systems are designed and manufactured to optimize the uniform field volume at a specified field and gap, for improved Spectroscopy and imaging performance, particularly with smaller Electromagnets and Power Supplies. Group3 High Precision Digital Probes can be used for closed-loop control with mG resolution and traceable calibration to 12T.
  • IECO BPS-40-100 Bipolar Power Supply. The BPS-40-100 is a high performance true 4-quadrant bipolar power supply with ±40V, ±100A output. When matched with the GMW 5203 Vertical Projected Field Electromagnet, the BPS-40-100 allows full excitation of the electromagnet to 100A. Depending on which pole style is used in the magnet, the resulting magnetic field at 4mm above the surface of the electromagnet ranges >0.8T at a single point to >0.53T over a 4mm, 1% uniformity disc.
  • GMW Projected Field Electromagnets can be integrated to multiple vendors probe stations, including with Celadon Systems VersaCore Probe Cards. A recording of GMW’s joint Webinar with Celadon Systems can be viewed here.

GMW offers Electromagnet Systems for magnetic material, thin film, and spintronics studies including the Miniature Projected Field Electromagnet family of: 5201 for in-plane fields; 5203 for vertical fields; 5204 for true 3-axis vector field; 5205 series for larger volume, modest vertical fields; and 5207 for vertical fields to +/-1T.

Dipole Electromagnets for FMR applications and full-wafer test are available with fields to +/-2T and true bipolar operation, along with HTS-110 Compact Electromagnets including Short Solenoids to +/-3T and Projected Field magnets to +/- 2T.

Additionally, we offer Bartington 3-axis AC/DC Helmholtz Coil Systems for sensor calibration, active magnetic field cancellation, or creating a known magnetic environment.

We also offer One- and Three-component Magnetic Sensors, Transducers and Field Mappers, including: Metrolab THM1176/1186 Three-Component Magnetic Field Probes with USB Interface and LabView software, full-scale, calibrated ranges of +/-100uT, +/-8mT, +/-3T and +/-14T; Senis One-, Two and Three-Component Hall Transducers with analog output, full-scale field ranges to +/-20T and frequency response from dc to 75kHz that can be used stand-alone or in Senis Magnetic Field Mapping Systems; and the Senis 3MTS hand-held USB 3-axis Teslameter, calibrated to 2T.
