摘要

Nano-structured Fe coverage was deposited on Pd/W{112} faceting surface for the investigation of magnetic properties. The morphology consisting of 3-sided nano-pyramids in Fe coverage remained stable at least up to 400 K. The Fe magnetization switched from perpendicular to in-plane direction at 2 physical monolayer (PML). Hydrogen adsorption significantly enhanced the perpendicular coercivity by 6-7 times, and shifted the switching critical thickness to 2.8 PML. The hydrogen thermal desorption and re-adsorption seriously influenced the magnetic behaviors, depending on the hydrogen partial pressure.
