Notes: Room temperature giant magnetoresistance (GMR) has been measured in small band-gap thin-film Hg1−xCdxTe (x∼0.1) samples with Corbino disk electrode configurations. The GMR exhibits a zero-field offset of as much as 350 G at room temperature. The resultant asymmetry in the field dependence of the GMR constitutes a self-biasing effect. We show that this self-biasing results from spatial composition fluctuations in the sample and that the bias effect can be controlled by selective doping and/or deposition masking. © 1996 American Institute of Physics.
