摘要: A dc voltage induced by an external ac current is observed in system of asymmetric mesoscopic superconducting loops. The value and sign this voltage, like the one persistent current, depend a periodical way on magnetic field with period corresponded to flux quantum within loop. amplitude oscillations does not frequency (in investigated region 100 Hz - 1 MHz) depends its amplitude. latter dependence monotonous. phenomenon rectification interpreted as consequence dynamic resistive state superposition current. It shown that can be added loops connected series: up 0.00001 V were single loop, 0.00004 3 0.0003 20
