摘要：

We have studied the effects of halogenizing HgBa2CaCu2O6+delta (Hg-1212) thin films and have found that the addition of chlorine/fluorine significantly enhances (1) the reproducibility and stability of Hg-1212 thin films, (2) the phase purity of Hg-1212 to over 90%, and (3) the magnetic critical current density (J(c,mag)) both at zero field and in-field. A possible mechanism of preventing contamination of precursor materials by chlorine/fluorine doping is proposed. (C) 1998 American Institute of Physics. [S0003-6951(98)02814-9].
