Magnetic field dependence of the electrical conductivity in V3Ge in the vicinity of H2c
Marchenko V. A., Nikulov A. V.
The excess electrical conductivity of V3Ge samples has been investigated experimentally in a perpendicular magnetic field ÐÅÁÇ#óÇ. At fields Η > 0.97 Hc2 the experimental data agree with theoretical calculations for the fluctuational conductivity. At Η = 0.97 #c2 the conductivity increases sharply and the critical current appears; this is attributed to a transition to a mixed state.
