Latest Patents
1. **Spin valve sensor having a nonmagnetic enhancement layer adjacent an ultra thin free layer**
This patent presents a spin valve device that includes a non-magnetic enhancement layer placed adjacent to an ultra-thin free layer. The design achieves a remarkable improvement in the giant magnetoresistance (GMR) ratio for free layer thicknesses below 50 Å, allowing electrons to maintain their spin state over longer distances. The strategic pairing of the enhancement layer material with the free layer minimizes low resistance pathways and enables alignment of the free layer with reduced magnetic fields, thus enhancing data density and bias point control.
2. **Hybrid dual spin valve sensor and method for making same**
Anderson's second patent details a hybrid dual spin valve sensor that integrates a standard spin valve and a synthetic spin valve sharing a common free layer. The structure includes multiple ferromagnetic and antiferromagnetic layers with carefully controlled magnetization orientations. The innovative processing methods for setting these orientations ensure the sensor can accurately detect resistance changes, paving the way for more sensitive data sensing technologies.
