Micromagnetic Study of Switching Mode Behavior on Perpendicularly Magnetized Nano-Dot at a Room Temperature

Abstract

Non volatile magnetic storage with high densities and fast rate data transfer is a primary need in recent computing technology. Perpendicular magnetized nano-dot is proposed to be an alternative media to make it real. The Switching mode behavior onperpendicularly magnetized nano-dot with volume 50 nm x 50 nm x 20 nm at a room temperature for magnetic storage application has been investifated by solved Landau Lifshift-Gilbert equation. The result is the material properties which quantitatively express as quality factor greatly affect the switching time. Critival value of quality factor become a boundary on the switching mode.
