The Modification of Magneto Impedance Effect with N Number Layer of Multilayers Structure [NiFe/Cu/NiFe]N/Cu/[NiFe/Cu/NiFe]N

Abstract

The effect of N number of layers [NiFe/Cu/NiFe]N/Cu/[NiFe/Cu/NiFe]N on the Magneto  Impedance (MI) ratio has been investigated. The multilayer structure was made using the  electrodeposition method on a meander patterned Cu PCB substrate. Measurement of the MI  ratio is performed at a low frequency of 100 kHz. The MI ratio increased from 1.34% for N = 1  to 1.86% for N = 3. This is because the increase in the number of N increases the permeability  of the sample, thereby increasing the MI ratio.
