摘要：

A review of theoretical models of giant magnetoimpedance (GMI) is presented. The whole frequency range from kHz to GHz is covered starting from the simple quasistatic models and ending with the complex dynamic models based on the simultaneous solution of linearized Maxwell and Landau-Lifshitz equations. The similarity between GMI and FMR is emphasized. The asymmetric GMI (AGMI) behavior is discussed in more detail. Three different mechanisms of asymmetry are outlined. Based on the theoretical results the rules for obtaining high performance GMI materials are put forward. (C) 2003 Elsevier B.V. All rights reserved.
