| Abstract: | A method of measuring magnetoresistance was introduced. Direct current power sapply, computerized X - Y recorder, electron magnet and temperature device were applied in our experiment. Measured the voltage of the standard resistance in series the circuit, it can be calculated the resistance of the sample under different temperature and the different magnetic field, then magnetoresistance can be computed. This measuring method is simple and accurate. |
| Keywords: | magnetoresistance a four-point probe two-point method |
