GE&R's Patented Line of Magnetocaloric Materials are the Lowest cost and highest performance Magnetocaloric Materials available on the market! We can synthesize magnetocaloric compositions with a peak performance at any temperature between 10K up to 330K. Please contact us if your desired peak temperture is not listed in the drop down menu and we can provide a quote. All products come with a Certificate of Analysis which includes the Delta S calculated from VSM data.
These magnetocaloric materials are available in various forms - 1) Bulk Ingot pieces (~5g-10g pieces), 2) Thin Plates (either 1inch or 0.5inch diameters), or 3) Powder form. For the Powder form, we can make the following size ranges: 700-1000um, 500-700um, 300-500um, 150-300um, 75-150um, 45-75um, and 25-45um. IF YOU ORDER THE POWDER - Please indicate in the notes the size range that you want. If you order sub-60K compositions - Please indicate your desired peak Temperature in the notes. We can synthesize these within +/-5 degrees of the temperature needed.
GE&R magnetocaloric materials have excellent stability and performance in magnetic systems. Bulk pricing is also available. These products are manufactured when ordered and will typically ship within 2-3 weeks of reciept of payment. Continued development is in progress to improve performance, lower cost, and provide custom forms. Please contact us with your specific needs.

- Temperature of delta S max anywhere between 10-330K
- Second Order Reversible Transitions (they behave like elemental Gd - no cracking or hysteresis!)
- Materials are fairly stable in air - we recommend storing in vacuum or inert gas.
- Large measurable delta T (>1 degree C in 1T field)
- Larger quantity bulk pricing available
- Available in usable forms: Sub-mm sized particles / Thin plates
IF YOU ORDER THE POWDER PLEASE LET US KNOW YOUR DESIRED SIZE
