20080271818 | Reorientation of Magnetic Layers and Structures Having Reoriented Magnetic Layers - Methods of reorienting ferromagnetic layers of a plurality of magnetoresistive elements and structures formed by the methods. The plurality of magnetoresistive elements, preferably GMR multilayer elements, are manufactured and arranged on a planar substrate. The method effectively allows selective orientation and reorientation of distinct ferromagnetic layers of a subset of the magnetoresistive elements on the substrate. The methods make either use of subsequent annealing processes making use of magnetic fields pointing in different directions. Prior to application of a subsequent annealing process, a complimentary subset of magnetoresistive elements is effectively shielded by selective deposition of a soft-magnetic shielding layer. Alternatively, a single annealing process can be performed when an externally applied magnetic field is locally modified by soft-magnetic structures, such as fluxguides. | 11-06-2008 |
20090032141 | Soft-metal electromechanical component and method making same - A three dimensional soft magnetic metal mass suitable for milling is formed wrapping soft magnetic metal ribbon into a three dimensional shape and then applying adhesive to the three dimensional shape. The adhesive permeates the three dimensional shape. The adhesive is then cured. If the soft magnetic metal mass is made as a toroid, then it could be processed into an electromechanical component. The electromechanical component would then be suitable for use in very high frequency electric motors. | 02-05-2009 |
