“…In case of the sinusoidal CPR (a) Llc/iPo determines the maximum number of flux quanta to penetrate, which in case of modified sinusoidal (b) and triangular (c) CPR is diminuished by LI2/iPo. For the triangular CPR we obtain nearly the same results as in case of modified sinusoidal CPR characterized by the same excess current (see [1], Fig. 6).…”
