This part of IEC 61788 is applicable to high-Tc Josephson junctions. It specifies terms, definitions, symbols and the measurement and estimation method for normal state resistance (Rn) and intrinsic critical current (Ici), based on a combination of selecting a data set from measured U-I curves with a geometric mean criterion and fitting a hyperbolic function to that data set.<\/p>\n
