Abstract

This study presents a new discovery of the super giant magneto-resonance effect observed at near resonance frequency in a magnetic LC-resonator consisting of a glass-coated amorphous Co_83.2B_3.3Si_5.9Mn_7.6 microwire with two capacitive terminal electrodes. The impedance measurement was carried out by an impedance analyzer. The magneto-impedance ratio (MIR) can be defined as MIR(H)=DeltaZ/Z(H_max)=1-|Z(H)/Z(H_max)|, where H_max is an applied maximum external magnetic field.
