| Abstract(in English) | We investigate the magnetoresistance for the magnetoresistive element, which consists of non-magnetic semiconductor, four electrodes and Au shunt, with varying location of voltage electrodes. The optimum location of voltage electrodes is estimated from MR ratios calculated by using finite element method. The MR ratio of 6.9 %, which is obtained at applied magnetic field of 0.005T for MR element with the asymmetrical voltage electrodes of the distance of 25 nm, is higher than that for the MR element with the symmetrical electrodes. In order to improve MR ratio at a low applied field, the flux guide type of MR element is proposed. The MR ratio of 138 % at an applied field of 0.005T is obtained for the flux guide type ele- ment with the asymmetrical electrodes. |
