摘要： Epitaxial ferroelectric and magnetic recording structures having graded lattice matching layers are disclosed. A single crystal material such as Si may be used as a substrate material upon which the graded lattice matching layers are deposited. The lattice matching layers may comprise metals and metal alloys, or may comprise oxides doped with selected elements or deposited under different oxygen pressures. A recording layer, such as ferroelectric lead zirconium titanate or a magnetic Fe/Pt multilayer structure, is deposited on the graded lattice matching layers.

摘要： An apparatus comprises a magnetic write pole, and a cooling device positioned adjacent to the magnetic write pole. The magnetic write pole can comprise a rare earth metal, or an alloy including a rare earth metal. A method of using a cooling device to increase a magnetic moment of a portion of a magnetic write pole in a magnetic recording head is also provided.
