摘要
Giant magnetoresistance or tunnel magnetoresistance (TMR) structures with magnetostrictive free layers are attractive approaches for the realization of novel strain sensors. It has been found that the strain response can he enhanced by using magnetostrictive materials such as Fe50Co50. First experiments have further revealed that the tunnel barrier of TMR Structures withstands a strain level of at least 0.1%. (C) 2002 Elsevier Science B.V. All rights reserved.
