For FMR damping measurements in traditional C-Frame Geometry, we offer GMW 3470 and 3480 magnets for lightweight perpendicular measurements up to 65 GHz. For angular dependence, we offer GMW 5403 and 5405 with high field across a gap large enough to allow for sample rotation. Alternatively, for experiments where sample rotation is not feasible, we offer a gimbal to allow the entire magnet to be rotated through a horizontal axis while being mechanically decoupled from the measurement.

For MOKE applications, a new Open Geometry 3480 version is available. This allows for both longitudinal and transverse MOKE in convenient geometry allowing greater access to sample.  An Extended Throat 3480 version allows for large diameter wafers to be inserted to gap, allowing for full coverage of 300mm wafer.

GMW offers modifications and customizations to all electromagnets in the GMW product range. We can modify standard poles with axial holes for optical access and custom pole shaping for ease-of-access. Additionally, pole tips and caps can be added for custom field profiles, such as maximum field at a single point or a uniform field over a larger area/volume. Yoke geometry can also be modified for increased access. Such customization allow for ease of integration and increased magnetic field performance. Examples include integration into vacuum systems, high field uniformity for EPR applications and access bores for samples or instrumentation.
