20090045899 | Thin film magnetic device and method of manufacturing the same - A thin film magnetic device is provided, in which magnetic permeability in a high frequency range can be easily improved. Scratch-like grooves extending along an extending direction of a coil (for example, a Y-axis direction being an extending direction of a second coil part) are formed at least one side of a surface and a back of each of a lower magnetic film and an upper magnetic film. A magnetization direction of anisotropic magnetization is controlled in each of formation areas of the scratch-like grooves (formation areas of lower magnetic films and upper magnetic films), and therefore displacement (rotation) of the magnetization direction of the anisotropic magnetization is pinned by the scratch-like grooves. Consequently, certain magnetic permeability is kept even in a high frequency range. Moreover, such formation of the scratch-like grooves may not cause complexity in manufacturing process. | 02-19-2009 |
20090197062 | Magnetic thin film and thin film magnetic device - A magnetic thin film includes: a first magnetic film formed on a substrate; and a second magnetic film formed on the first magnetic film. The first magnetic film is a soft magnetic film having magnetic permeability higher than that of the second magnetic film. The second magnetic film is an iron-based soft magnetic film. Thickness ratio between the first magnetic film and the second magnetic film (=thickness of the first magnetic film/thickness of the second magnetic film) lies in a range of 0.005 to 0.030 both inclusive. | 08-06-2009 |
