摘要:We observed the giant magnetoimpedance and colossal ac magnetoresistance for a Cu coil wound on La-0 Sr-67(0) 33MnO3 under low dc magnetic fields Even though the dc magnetoresistance Delta R/R-0 for La-0 Sr-67(0) 33MnO3 plate is only -2 4% under H = 12 kOe a Cu coil wound on La-0 Sr-67(0) 33MnO3 plate exhibits a colossal ac magnetoresistance Delta R/R-0 of-93% at 10 MHz and a giant magnetoimpedance Delta Z/Z(0) of -59% in a wide frequency range of 500 kHz-10 MHz under a longitudinal field H = 600 Oe The transverse magnetoimpedance is weaker than the longitudinal one The giant magnetoimpedance and colossal ac magnetoresistance for a Cu coil wound on La-0 Sr-67(0) 33MnO3 are connected with the variation of permeability induced by dc magnetic field (C) 2010 Elsevier Ltd All rights reserved
