摘要:
Als Stellungssensor wird ein Spulenkern (8) für eine induktive, frequenzunabhängige Schaltvorrichtung vorgeschlagen. Um den in langen, weichmagnetischen und unter Zugspannung stehenden Drähten bekannten frequenzunabhängigen Ummagnetisierungseffekt auch für relativ kurze draht- bzw. stabförmige Körper ausnutzen zu können, ist der Spulenkern (8) aus einem Verbundkörper (9) aus gegeneinander mechanisch verspannten weichmagnetischen Materialien (1, 2) und einem Dauermagneten (3) zusammengesetzt. Hierdurch ist es möglich, einen Spulenkern mit einer Länge von weniger als 30 mm herzustellen, der auch bei langsamer Feldänderung in einer den Spulenkern umgebenden Spule einen Spannungsimpuls induziert.
摘要:
Described is an apparatus which comprises: an input ferromagnet to receive a first charge current and to produce a corresponding spin current; and a stack of metal layers configured to convert the corresponding spin current to a second charge current, wherein the stack of metal layers is coupled to the input magnet.
摘要:
The invention relates to a storage cell arrangement comprising a magnetoresistive element (11) which has a ring-shaped cross-section in a stratified plane. A first line (12) and a second line (13) which intersect each other are provided in said storage cell arrangement. The magnetoresistive element (11) is located in the intersection area between the first line (12) and the second line (13). Said first line (12) and/or said second line have at least one first line section (131) in which a current component which is oriented parallel to the stratified plane is predominant and a second line section (132) in which a current component which is oriented vertically to the stratified plane is predominant.

Integrated circuit memory elements are fabricated by disposing a first layer of electrically conductive material on the surface of an electrically insulating substrate. The first layer of electrically conductive material is formed into a first predetermined pattern. A second layer of electrically insulating material is disposed on the surface of the electrically insulating substrate and the patterned first layer of electrically conductive material. A first layer of magnetizable material is disposed on the second insulating layer and is formed into a predetermined pattern having a predetermined positional relationship with respect to the underlying patterned first layer of electrically conductive material. A third layer of electrically insulating material is disposed over the second layer of insulating material and the patterned first layer of magnetizable material. Openings are formed in the underlying layers of insulating material to expose predetermined electrical contact areas on the underlying patterned first electrically conductive layer. A second electrically conductive layer is disposed over the third layer of electrically insulating material into the openings and into electrical contact with the exposed electrical contact areas of the underlying patterned first electrically conductive layer. The second electrically conductive layer is formed into a second predetermined pattern having a predetermined positional relationship with respect to the underlying patterned layer of magnetizable material and the patterned first electrically conductive layer. The patterned first electrically conductive layer and the patterned second electrically conductive layer define at least two conductive windings disposed about the patterned magnetizable material.
摘要:
An in-process magnetic layer (460, 462) having an in-process area dimension (DR1) is formed with a chemically damaged region at a periphery. At least a portion of the chemically damaged region is transformed to a chemically modified peripheral portion that is non- ferromagnetic (4604, 4624). Optionally, the transforming is by oxidation, nitridation or fluorination, or combinations of the same.
