Target of intermetallic compound with B2-ordered lattice structure, production method thereof and magnetic recording medium having B2-structured underlayer

摘要

A target for sputter-depositing a B2-structured thin film for an underlayer of a magnetic recording medium. Since the target is made of a sintered body of an intermetallic compound being substantially a B2-ordered lattice structure, the target has a uniform small grain size and a high bending strength. The target produces a thin film with a small grain size and a minimized particle deposition.
