摘要： The invention includes improving or enhancing exchange coupling within a thin film layer. The improvement or enhancement to the exchange coupling occurs between the grains that are deposited to form the thin film. The improvement or enhancement to the exchange coupling between the grains of the thin film results from annealing the thin film at an elevated temperature for a period of time. A thin film structure and/or a magnetic recording layer made in accordance with the invention are disclosed.

摘要： An apparatus includes a plurality of bilayer structures positioned adjacent to each other, each of the bilayer structures including a first layer of magnetic material having a first Curie temperature and a second layer of magnetic material positioned adjacent to the first layer, wherein the second layer has a second Curie temperature that is lower than the first Curie temperature, and magnetic grains of the first layer are unstable when the second layer of magnetic material is heated above the second Curie temperature. The recording temperature is reduced due to the smaller switching volume achieved by using vertically decoupled laminations at elevated temperatures.
摘要翻译：一种装置包括彼此相邻定位的多个双层结构，每个双层结构包括具有第一居里温度的第一层磁性材料和邻近第一层定位的第二层磁性材料，其中第二层具有第二居里温度低于第一居里温度时，当第二层磁性材料被加热到高于第二居里温度时，第一层的磁性颗粒是不稳定的。由于在升高的温度下使用垂直去耦的叠片来实现较小的开关体积，所以记录温度降低。
