Abstract
Provided are magnetic sensors, which include a magnetic sensor element having a sensor surface modification and an inter-element area adjacent to the magnetic sensor element and having an inter-element area surface modification, where the sensor surface modification and the inter-element area surface modification provide a binding surface in the inter-element area. Also provided are devices, systems and methods in which the subject magnetic sensors find use.
Claims27
A magnetic sensor comprising:
- a magnetic sensor element comprising a sensor surface modification;
- an inter-element area adjacent to the magnetic sensor element and comprising an inter-element area surface modification;
