Magnetic coercivity of focused ion beam irradiated lines in a Pt/Co(1.4 nm)/Pt film
Original language description
Regular sets of ultranarrow lines have been patterned on a Pt/Co(1.4 nm)/Pt ultrathin magnetic film by focusing a Ga+ ion beam (FIB) at different fluences. Ga+ ion irradiation is known to soften magnetic properties in such films. Even at low Ga+ ion fluence, and as proved by atomic force microscopy, the transverse perturbed region in the lines is much wider than calculated by Stopping and Range of Ions in Matter (SRIM) simulations, demonstrating that a swelling effect superimposes to more localized irradiation damages. Field-induced magnetization reversal and static or dynamic coercivity of these FIB lines separated by nonirradiated ferromagnetic tracks have been investigated by polar MOKE microscopy. The nucleation of small reversed domains is much easier in FIB lines irradiated at high fluence, and a remnant domain structure can be stabilized in that case.
