Abstract


  • Underdoped BaFe1.9Co0.1As2 single crystal was studied by angular dependence of

    magneto-transport at fields up to 13 T over a wide range of temperature. Our results show that

    pinning potential, Uo, decreases slightly for h45 and remains constant for h45, while

    the upper critical field, Hc2, and the irreversibility field, Hirr, increase with h. According to

    anisotropic Ginzburg-Landau theory, the anisotropy was determined by scaling the resistivity

    under different magnetic fields below the superconducting critical temperature, Tc. Anisotropy,

    C, in the underdoped crystal is found to be temperature dependent and decreases from

    2.1 to 1.8 for as T is reduced from 17 to 12.5 K.
