摘要：
Very concise formulations for the bias voltage or/and temperature dependences of tunnel magnetoresistance ratio and resistances were deduced based on a spin-polarized tunneling model and an anisotropic wavelength-cut off energy E-c(7) of a spin-wave spectrum in magnetic tunnel junctions (MTJs). The main intrinsic magnetoelectric properties of MTJ can be self-consistently evaluated using these concise formulations. (C) 2002 Elsevier Science B.V. All rights reserved.
