Abstract
Exchange coupling of Mumetal(Ni77Fe14Mo5Cu4 wt%)-Al oxide-Co multilayer has been investigated as Mumetal growing temperature increases from 20 °C to 90 °C. As Mumetal growing temperature increases, grain size and surface roughness increase simultaneously. The increase of grain size diminishes the exchange coupling until 40 °C, and the increase of roughness increases the exchange coupling after 40 °C. It is thought that grain size and roughness of the underlayer are competing factors for the interlayer exchange coupling of the magnetic multilayer.
