Abstract
An all-quadrant measurement method for a middle-large magnetic field includes the steps of placing four orthogonally configured magnetic resistances in an external magnetic field; determining two magnetic resistances with the minimum resistance values, thereby determining that the other two magnetic resistances are in an S1 status, and making resistance values of the two magnetic resistances which are in the S1 status be R1 and R2, and at the same time taking an initial reference layer magnetization direction of the two magnetic resistances as a given reference layer magnetization direction when there is no magnetic field; respectively calculating an included angle between a free layer magnetization direction and the reference layer magnetization direction of the two magnetic resistances; respectively calculating the free layer magnetization direction of the two magnetic resistances; and solving a magnetic field amplitude and direction of the external magnetic field.
