Exchange-coupled SmTbCo dual-layer media are prepared by an r.f magnetron sputtering system and their magnetic properties are investigated. The prepared SmTbCo dual layer is composed of a 340emu/cm3 TM-rich readout layer and a 5.80kOe RE-rich memory layer, meeting the requirements of high saturation magnetization and large coercivity for hybrid recording. Through exchange coupling, the coercivity of the high-saturation-magnetization SmTbCo layer is greatly enhanced from 1.85 to 5.96kOe. The calculated interface wall energy for Sm6.65Tb12.35Co81...

联合交换的 SmTbCo 双层的媒介被 r.f 准备磁控管劈啪作响系统和他们的磁性被调查。准备 SmTbCo 双层由 340 食火鸟 / 厘米 3 组成 TM 富有的读出层和 5.80 kOe 重新富人记忆层，为混合记录满足高浸透磁化和大 coercivity 的要求。通过联合的交换， high-saturation-magnetization SmTbCo 层的 coercivity 极大地从 1.85 ～ 5.96 kOe 被提高。为 Sm 6.65 Tb 12.35 公司 81(20 nm )/Sm 1.22 Tb 42.16 公司 56.62(20 nm ) 是大约 3.85 尔格 / 厘米 2 。SmTbCo 联合交换的双层的电影的颠倒磁化基于一个微磁性的模型被分析。
