摘要：
Two-dimensional electron gas systems modulated by a lateral magnetic superlattice are proposed and the related magnetoresistance effect is described in this work. It is found that the magnetoresistance (MR) ratio of the given structures depends strongly on the uniform magnetic field, and the peaks of the MR ratio depressed linearly with the increase of the uniform magnetic field. This feature can be utilized in practical linear magnetoresistance (LMR) devices. (C) 2011 Elsevier Ltd. All rights reserved.
