Magnetoresistive Read Heads: Fundamentals and Functionality

Enhancement of thermal robustness in magnetic tunnel junctions with perpendicular magnetic anisotropy

“…is the key figure of merit to evaluate the AMR effect. The relatively large magnetoresistive coefficient and small magneostriction effect for Ni 81 Fe 19 leads to a shift from inductive head technology towards MR-based read heads [62][63][64]. Note that in the absence of H ext , the average resistivity of a demagnetized sample would be || 12 33…”
