Abstract: PURPOSE:To improve easily the magnetic characteristic of the titled magnetic thin film by providing a conductor layer on a substrate and depositing a magnetic thin film while impressing a DC negative voltage on the conductor layer. CONSTITUTION:Chromium is deposited in 500Angstrom  thickness on a substrate 2 as a conductor layer 1 by vapor deposition.
