Idealized tetragonal body-centered crystal structure of the perovskite type .13
Temperature dependence of the electrical resistance of in two scales.
Temperature dependence of the magnetization of in two scales, measured in a field in the ZFC (●) and FC (○) regimes.
Temperature dependence of the reciprocal of the magnetic susceptibility of , measured in two regimes: ZFC (●) and FC (○).
Temperature dependence of the real (a) and imaginary (b) parts of the susceptibility of , measured in field.
Typical temperature set of point-contact spectra for one of the samples. For clarity, the curves are shifted by an arbitrary amount along the vertical axis. The temperature is shown on each curve. The dotted curves show the dependences computed according to the BTK theory.
Temperature dependence of the order parameter of a sample: experiment (◼) and BCS calculation (—).
Temperature dependence of the specific heat of a sample.
Point-contact spectra of versus the magnetic field at temperature . For clarity, the curves are shifted along the vertical axis by an arbitrary amount. The magnetic field is indicated on each curve. The dotted curves represent the dependence is computed according to the BTK theory.
