Magnetic Domain Evolution of Terfenol-D with the VFM

MFM phase images of the Terfenol-D disk under a series of in-plane VFM fields perpendicular to the
Magnetization. (a) MFM phase images taken at 2000 G and (b) after its removal; (c) MFM phase images
taken at -2000 G and (d) after its removal. The direction of the magnetic field is indicated by the arrow.
Imaged with MFP-3D AFM, 10µm scan.
