چکیده انگلیسی
This paper presents a method of heat-assisted magnetic probe recording on perpendicular medium. Electrical current from scanning tunneling microscope (STM) is employed as the major heating source. Recording medium is a strongly-coupled CoNi/Pt multilayered film. Pulses with amplitude of 3–7 V and duration of 200 ns were applied between the STM tip and the recording medium. Experiments show that magnetic marks with an average size of 184 nm were formed for voltages above 4 V. A model is built to simulate the formation of magnetic domains in the processing of probe-based magnetic recording. Simulation results agree with experiments well.
