我们用Muon-Spin旋转方法研究了[FeCp2*][TCNq]的变磁相变，其中Cp*=C5Me5，TCNq为7，7，8，8-四氰基-对-奎诺二甲烷。这种电子转移盐含有交替的[FeCp2*](+)阳离子和[TCNQ](-)阴离子的平行链。我们的零场mU-SR数据显示了2.5K的跃迁，并表明在2.5K以下发展了一个静态的、但无序的内场分布。我们还用高横场mU-SR研究了变磁相变，并给出了内场分布在相变过程中的变化情况。(C)2005 Elsevier B.V.保留所有权利。
We have used muon-spin rotation (mu SR) to study the metamagnetic transition in [FeCp2*][TCNQ] where Cp* = C5Me5 and TCNQ is 7,7,8,8-tetracyano-p-quinodimethane. This electron-transfer salt contains parallel chains of alternating [FeCp2*](+) cations and [TCNQ](-) anions. Our zero-field mu SR data show the 2.5 K transition and show that a static, but disordered, internal field distribution develops below this. High-transverse-field mu SR has also been used to study the metamagnetic transition and the data illustrate how the internal field distribution changes through this transition. (c) 2005 Elsevier B.V.
