Abstract

A voltage pulse generator for magnetic field application was built using a coaxial cable as a capacitor. The pulse duration was fixed to 10 ns and the pulse field rise time was controlled from 70 ps to 4 ns using low-pass filters. Magnetization switching experiments were carried out on a Co/Pt multilayer dot with diameter of 300 nm with a perpendicular pulse field. The required pulse field amplitude for magnetization switching is independent of the pulse rise time, suggesting that the thermally activated process is dominant in the perpendicular field geometry.
