The application of piezoremanent magnetization to magnetic contact printing

Piezoremanent magnetization (i.e., remanent magnetization obtained by the simultaneous application of a momentary pressure and a magnetic dc field) was studied for application to magnetic contact printing. A Co-γFe2O3tape was found most suitable for the slave tape, and the origin of the piezoremanent magnetization effect was attributed to the inverse magnetostrictive effect, the dispersion of Co atoms to vacant lattices, and crystalline anisotropy.
