在本文中，我们研究了位图案化介质、陷阱电子辅助磁记录(TEAMR)和使用介质底层的改进的TEAMR(M-TEAMR)介质的矫顽力。吸血鬼磁模拟器被用来模拟三种记录比特结构，并使用原子自旋模型来研究M-H回路。结果表明，M-TEAMR和TEAMR的磁开关量与比特大小有关。对于所有比特大小，M-TEAMR中的磁开关减少的百分比也大于TEAMR。对于1.6×1.6×3.2 Nm~3的比特大小，M-TEAMR的磁开关减少百分比大约是TEAMR的4倍。
In this paper, we study the coercivity of bit-patterned media, trapping electron-assisted magnetic recording (TEAMR), and modified TEAMR (M-TEAMR) media using a dielectric underlayer. The VAMPIRE magnetic simulator is used to model three structures of recording bits and to study the M-H loops using an atomistic spin model. The results show that the magnetic switching reduction in M-TEAMR and TEAMR depends on the bit size. The percentage of magnetic switching reduction in M-TEAMR is also larger than TEAMR for all bit sizes. For a bit size of 1.6 × 1.6 × 3.2 nm3, the percentage of magnetic switching reduction in M-TEAMR is approximately four times higher than that in TEAMR.
