|Issue Date:||15-May-2005||Citation:||Cheng, X.Z., Jalil, M.B.A. (2005-05-15). The effect of thermal fluctuation on tilted perpendicular media. Journal of Applied Physics 97 (10) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.1852853||Abstract:||We investigated via micromagnetic simulation the effect of thermal fluctuation on the stability and transition width of a tilted media with easy axis oriented at 45° and 135° with respect to the vertical along the down-track direction. A dynamic model of the recording process is presented which incorporates a Westmijze head field rotated by 90°. Thermal fluctuations are modeled via a stochastic Landau-Lifshitz-Gilbert equation with a temperature-dependent white-noise field. The dependence of the transition parameter a between adjacent bits and signal-to-noise ratio on temperature is investigated, and comparison between these values of the perpendicular medium and those of the two types of tilted media is performed. © 2005 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/71974||ISSN:||00218979||DOI:||10.1063/1.1852853|
