Abstract
A laser-programmable magnetoresistive device includes a substrate, a magnetoresistive sensor, and a thermal control layer sequentially arranged in a stacked manner. A non-magnetic insulating layer for electrical isolation is provided between the magnetoresistive sensor and the thermal control layer. The magnetoresistive sensor is composed of a magnetoresistive sensing unit, which is a multilayer thin-film stacked structure containing an anti-ferromagnetic layer. During laser programming, parameters of the thermal control layer and/or the magnetoresistive sensor are varied to change the thermal response produced by the laser on the magnetoresistive sensor, to increase or decrease the temperature of the magnetoresistive sensor at the same laser power. The film parameters used include material composition and film thickness. High precision laser programming of a magnetoresistive sensor is obtained, with improved magnetoresistive sensor manufacturability, improved magnetoresistive sensor noise performance, and improved magnetoresistive sensor detectability.
