摘要

An improved thick film sensor for detection of magnetic bubble domains which can be configured to provide soft error detection and full data rate sensing. The sensor can be fabricated using single level masking techniques and is typically a magnetoresistive sensor comprised of NiFe. In its basic configuration, the sensor is comprised of two sets of magnetoresistive elements, each set including a sensor element and a dummy element, where both the sensor element and the dummy element provide a signal due to the bubble domain to be sensed. The magnetoresistive elements are arranged in a bridge circuit to give full data rate sensing and soft error detection. In a preferred embodiment, chevron expander-detectors are used, although the geometry of the sensor and dummy elements is not limited to chevron-type geometries.
