Abstract

A method for manufacturing a magnetic film includes preparing a foundation layer containing a noble metal element and a base metal element, and depositing a plated layer of a magnetic material on the foundation layer by pulse plating.

Claims (10)

1. A thin-film magnetic head, comprising:

a write element;

a read element, and;

a slider supporting said write element and said read element, wherein

at least one of said write element and said read element includes a magnetic film including a foundation layer consisting of an alloy of a noble metal element and a base metal element, and a plated layer of a magnetic material substantially consisting of CoFe or NiFe formed on said foundation layer,

wherein said foundation layer is selected from a combination group of (Ru, Ti),

wherein a total amount of said base metal element in said foundation layer ranges from 5 to 20 atomic %, and

wherein said foundation layer has a lower standard electrode potential than a foundation layer of only said noble metal element to suppress an occurrence of pinholes in said plated layer when said plated layer is formed on said foundation layer.

2. The thin-film magnetic head of claim 1 , further comprising:

a second layer of a magnetic material formed directly on said plated layer, wherein said plated layer is formed directly on said foundation layer.
