<p><P>PROBLEM TO BE SOLVED: To provide a magnetoresistance effect element that has high accuracy and can be easily formed, and a magnetic field detector, position detector, rotation detector, and current detector using the same. <P>SOLUTION: A magnetoresistance effect element 1 includes four or more ferromagnetic layers 8, and three or more tunnel insulation layers 9 provided between the four or more respective ferromagnetic layers 8. In a state where a magnetic field Hex is not applied from the outside, magnetization 11 directions of the ferromagnetic layers 8 that sandwich the three or more respective tunnel insulation layers 9 and oppose the corresponding ferromagnetic layers 8 are mutually opposite directions. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
