Transition curvature in heat assisted magnetic recording presents significant limitation from reaching desired track densities and linear densities [1][2].
Heat-assisted magnetic recording (HAMR) has been widely touted as a leading candidate for enabling the next generation of ultra-high density data storage [1]. To fully assess the advantage and potential of HAMR technology and to understand the physics of the HAMR recording process, extensive Landau-Lifshitz-Bloch (LLB) equation-based micromagnetic modeling has been conducted [2]. Fundamental recording...
This paper presents detailed micromagnetic analysis of the magnetization reversal characteristics and recording properties and comparison with the conventional granular perpendicular media (GPM) will be discussed. The percolated perpendicular media (PPM) consists of exchange coupled magnetic grains with strong perpendicular anisotropy and, more or less uniformly and relatively densely distributed...
In this paper, the MRAM design utilizes material intrinsic perpendicular anisotropy is analyzed via micromagnetic simulation with inclusion of spin momentum transfer effects.
