A mu SR study of the metamagnetic phase transition in the electron-transfer salt [FeCp2*][TCNQ]

Conference item

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.
