The magnetic field sensor which possesses the enormous reluctance effect

摘要

(57) Abstract This magnetic detector has magnetic anisotropy inside the surface and the 1st thin layer element which was drawn up with the magnetic material which possesses two easy magnetization axes inside this aspect and includes the 2nd thin layer element (1 and 2). One coercion boundary among these elements that of the other element has the value which differs. Two elements are done, stretching when there is no magnetic field, it is vertical to the direction of those easy magnetization axes, have possessed parallel form mutually. As for width of these elements, when at least one element there is no external magnetic field, is kind of something which tries to possess the magnetization which orientation is done according to the length of that element. Application example: Measurement figure 1b of magnetic field
