We have measured the electrical resistivity, Hall effect and transverse even voltage in the flux-flow state of CeRu2, CeCo2 and Yb3Rh4Sn13. In all the transport properties, we found a clear anomaly related with the peak effect, which was argued in relation to the inhomogeneous superconducting phase proposed by Fulde-Ferrell and Larkin-Ovchinnikov. The pinning force and the transverse even voltage depend largely on sample quality. A deviation from the ordinary BCS prediction, suggesting an anisotropy in the superconducting gap, has been found in the specific heat of CeCo2.
