LEEM-8 Magnetoresistive Effect Experimental Apparatus
Note: oscilloscope not included
The device is simple in structure and rich in content. It uses two kinds of sensors: GaAs Hall sensor to measure the magnetic induction intensity, and to study the resistance of InSb magnetoresistance sensor under different magnetic induction intensity. Students can observe the Hall effect and magnetoresistance effect of semiconductor, which are characterized by research and design experiments.
