New Lake Shore eBook Discusses the FORC Measurement and Analysis Method

First-order-reversal-curve (FORC) measurements have become indispensable for characterizing interactions and coercivity distributions in a wide array of magnetic materials.

Lake Shore Cryotronics has released a new eBook, “Magnetometry Measurements and First-Order-Reversal-Curve (FORC) Analysis,” which discusses the most commonly used magnetometry measurement techniques and the FORC measurement. The resource also presents measurement results for magnetic materials such as nanoparticle-based nanocomposites, permanent magnets, multi-phase ferrite magnets, and magnetic nanowire arrays.

The eBook is available for free download at:

Additionally, Lake Shore has made available an app note that presents typical noise measurement results and hysteresis loop measurements of low-moment magnetic materials using Lake Shore’s new 8600 Series VSM. Based on extensive in-house performance testing, Lake Shore has updated the noise floor spec of the 8600 Series to 25 nemu. This level of sensitivity, and the resulting measurement speed of the 8600 Series VSM, particularly benefits FORC measurements.
