First-order-reversal-curve measurements of nano-magnetic materials
September 11, 2014
The magnetic characterization of nanoscale materials is usually made by measuring a hysteresis loop. It is not possible to obtain interaction or coercivity distribution information from the hysteresis loop alone, however.
First-order-reversal-curves (FORCs) provide insight into the relative proportions of reversible and irreversible components of the magnetization of a material. This paper will discuss the FORC measurement technique and subsequent analysis, which lead to the FORC diagram, and present examples of measurement results for different magnetic materials.
