Аннотация:We present results of the investigation of new magneto-transport phenomena. namely, the electrode potential (EP) of ferromagnetic electrodes dependence on the external magnetic field. This effect was observed by Perov N. S. in 19941 for the Fe-electrode in the magnetic field 3 kOe and the experimental EP value was 20 mV. which is 3 orders more in com parison with the theoretical estimation. In this work it is shown that the EP depends on the magnetic field value non-linear (up to 8 kOe), on the electrodes materials (Fe, Co, Ni and some alloy were investigated) and also on the composition and concentration of electrolytes (FeCl3, H2SO*, NaCl and HNO3 were used). The EP hysteresis is not the same as magnetization hysteresis loops and besides the significant relaxation of EP have been found. We measured the EP relaxation at velocities of the magnetic field variation from 10 to 200 Oe/sec. The phenomenological model was used for explanation of all results. Some sensors are discussed which used this effect. The construction of magnetic head and magnetic field sensor are suggested. The results of model magnetic field sensor
testing are described. Research supported by RFFI.
