First-Order-Reversal-Curve (Forc) Studies of Nanomagnetic Materials

Dodrill B., Lake Shore Cryotronics, US

The magnetic characterization of nanoscale materials is usually made by measuring a hysteresis loop. However it is not possible to obtain information of interactions or coercivity distributions from the hysteresis loop alone. Studies of magnetic [...]

High-Temperature First-Order-Reversal-Curve (FORC) Study of Magnetic Nanoparticle Materials

Dodrill B., Ohodnicki P., Lake Shore Cryotronics, US

First-order-reversal-curves (FORC) are an elegant tool for characterizing the magnetic properties of materials. The technique has been extensively used to investigate the magnetic properties of natural samples because it can distinguish between different domain states [...]
