  • Stack including a magnetic zero layer
    Patent number: 9734857
    Abstract: A stack including a crystallographic orientation interlayer, a magnetic zero layer disposed on the interlayer, and a magnetic recording layer disposed on the magnetic zero layer is disclosed. The magnetic zero layer is non-magnetic or has a saturation magnetic flux density (Bs) less than about 100 emu/cc. The magnetic zero layer and the magnetic layer include grains surrounded by a non-magnetic segregant. The magnetic zero layer provides a coherent interface between the interlayer and the magnetic layer with a lattice mismatch less than about 4%.
    Type: Grant
    Filed: July 24, 2015
    Date of Patent: August 15, 2017
    Assignee: SEAGATE TECHNOLOGY LLC
