Abstract : The patent describes a thin-film raster pattern magnetoresistor device produced from an electron beam-recrystallized InSb film employing a photolithographic process to etch out of the InSb film a suitable pattern on which micron-size indium or copper stripes are later etched from a superposed metallic film applied on the InSb by vacuum deposition. The thin-film raster pattern magnetoresistor, device is a resistor, whose initial resistance in zero magnetic field is between 10 and 1,000 ohms, and whose resistance increases with an applied magnetic field, reaching a value greater than a factor of 10 on the initial resistance in a magnetic field of 10 kOe.
