Abstract
CoCrTa and CoCrTaSm sandwich films were deposited using rf sputtering on glass slides with an underlayer of platinum and a CoNbFe base layer . The films were deposited at room temperature. The magnetic propertie s and microstructures of the films are reported. The main result is th at the addition of small quantities of samarium can increase the perpe ndicular coercivity from 350 to 1250 Oe. This makes the films more sui table for high-density magnetic recording.
