MAGNETORESISTANCE EFFECT DEVICE AND MAGNETIC FIELD DETECTING EQUIPMENT

摘要: PROBLEM TO BE SOLVED: To obtain a magnetoresistance effect device which shows linear bias characteristics wherein dynamic range is sufficient and noise little, with excellent reproducibility, when the element operated by sense current MR decrease due to heat generation little. SOLUTION: In GMR 20, soft magnetic material layer 14 for applying bias, non-magnetic intermediate 13, buffer 16 an artificial grid film (GMR layer) 12 conductive layers 12a 12b are alternately formed in this order.
