Microwave assisted magnetic recording (MAMR) technology, with microwave generated by the spin transfer oscillator (STO) as energy assisted source, is potential for future magnetic recording technique.
Microwave assisted magnetic recording (MAMR) is a promising candidate to achieve the areal density above 1Tb/in2 [1]. Nowadays CoX/Pt multilayer is chosen as the media for STO MAMR due to its ultrahigh interfacial anisotropy [2]. In this paper, a micromagnetic model is utilized for recording simulation on high anisotropy (Hk >25 kOe) CoX/Pt media, with Voronoi polycrystalline built up based on...
The CoX/Pt multilayer (X here represents the doping element to form grain boundary) is considered as the potential future medium owing to its high interfacial perpendicular anisotropy [1] utilized in magnetic assisted magnetic recording (MAMR) [2]. Meanwhile, microwave assisted reversal in Co/ Pt and Co/Pd has been reported in experiments [3,4]. The magnetic property and its writability of the CoX/Pt...
