AC Susceptibility Investigations of Superconducting Doped Fullerenes A(X)C(60)
We present investigations of the real and the imaginary parts of the complex ac magnetic susceptibility chi=chi’ - i chi" of granular fulleride superconductors K3C60 and Rb3C60. The magnetic response chi(T) has been studied as a function of the alternating magnetic field amplitude (0.01 G - 20 G), the driving field frequency (10 Hz - 1 kHz) and external magnetic de fields (up to 14 T). From this we determined the upper and lower critical fields and the critical current densities.
