Numerical Simulation Study of Magnetization Precession Dynamics in Submicron Elliptical Ni{sub}80Fe{sub}20 Thin Film Elements

摘要

Studies of magnetization configuration and ultrafast switching mechanism of small patterned magnetic elements at submicron or nanoscale have become subjects of great interest, both due to the scientific interest and future technological applications in magnetic sensors and nonvolatile magnetic random access memory (MRAM) devices. Recently there have been many efforts to reduce the precession of the magnetization by using the concept of switching field pulse adjustment, and an in-depth understanding of the reversal mechanisms influenced by the suppression of the magnetization ringing is of great interest.
