Abstract
The interplane resistivity (Formula presented) and in-plane resistivity (Formula presented) of the layered superconductor (Formula presented) were studied at 50 mK under magnetic fields B up to 33 T applied parallel to the conducting plane. The superconductivity recurrence predicted theoretically was not observed for either (Formula presented) or (Formula presented) in magnetic fields up to 33 T. In the normal-state transverse magnetoresistance of (Formula presented) a pronounced anisotropy was found within the conducting plane. A sharp resistance peak with an apex in the direction of the parallel field and a superlinear field dependence at the peak were observed with a magnetic field in the [110] direction, while this peak was absent with a magnetic field parallel to the [100] direction. The results are discussed in terms of the in-plane anisotropy of the interplane transfer energy (Formula presented) For (Formula presented) the longitudinal magnetoresistance with the current both in the [110] and [100] directions increased notably, which is incompatible with semiclassical behavior.
