Inventor: SEYAMA YOSHIHIKO
IPC: G01R33/09
Filed: 2000-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a CPP structural spin valve head, by which the large resistance variation is surely obtainable by the small number of laminated layers. SOLUTION: In the CPP structural spin valve head 36, a sense current goes through an insulated layer 54. The movement of electron across the insulated layer 54 is supposed to be realized by the operation of the minute defect, i.e., a pin hole formed on the insulated layer 54. The current is concentrated to the pin hole. Thus, in such spin valve head 36, the large resistance variation is realized in accordance with the inversion of the magnetizing direction established in a ferromagnetic layer 56 at the free side, similarly in the case the passing cross sectional surface of the current is reduced. This sort of the CPP structural spin valve head 36 remarkably contributes to the further increase of density of the magnetic recording. In this spin valve head 36, the resistance value is reduced as compared to that of a so-called tunnel junction magneto- resistance effect element.  The generation of thermal noise is suppressed.
