Antiferromagnetically coupled magnetic recording media with cocrfe alloy first ferromagnetic film

用于数据存储的磁记录介质使用一种至少包含两层铁磁膜的磁记录层，这两层铁磁膜通过非铁磁间隔膜反铁磁交换耦合在一起。在这个反铁磁耦合(AFC)记录层中，两个铁磁膜的磁矩反平行，于是AFC记录层的净剩余磁化强度-厚度积(Mrt)是这两层铁磁膜的Mrt的差值。Mrt的这个缩减不会降低记录介质的热稳定性。AFC记录层中的下部铁磁薄膜是铁磁CoCrFe合金，在其与Cr合金底层之间不需要晶核形成层。以CoCrFe合金作为AFC记录层中的第一或下部铁磁薄膜的方式减小了固有的介质噪声。 A magnetic recording medium for data storage uses a magnetic re...
