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 Co83.2B3.3Si5.9Mn7.6 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(Hmax)=1-|Z(H)/Z(Hmax)|, where Hmax is an applied maximum external magnetic field.
