原始语种摘要: SUMMARY(#br)The magnetization reversal process of Nd‐Fe‐B magnets has been long discussed. Since the elemental steps of the magnetization reversal process such as a nucleation of reversed embryo and a wall depinning are the events as small as nanometer scale and as fast as nano/sub‐nanosecond time scale, the study on the magnetization reversal with these space and time regions is essentially important. In this work, a generation of large amplitude nanosecond pulse field and a fabrication of Nd‐Fe‐B nanodot were examined, and then the magnetization reversal process of the Nd‐Fe‐B nanodot under the nanosecond pulse field was investigated. Combination of a Blumlein transmission line and a micro‐coil enables to generate a pulse field of 0.87 T in amplitude and 6 ns in width. It was clearly...
