Effect of ferrite layer thickness on the magnetic properties of SnO2/Cu-Zn ferrite multilayer
Abstract
Multilayers of SnO2/Cu-Zn ferrite were deposited using rf-sputtering. The resonance field and the interlayer coupling decrease with increasing CZF layer thickness. The saturation magnetization initially increases and then saturates with increasing CZF layer thickness. The dead layer thickness and the bulk magnetization values estimated using dead layer model are 8 nm and 56 emu/cc respectively.
