Stack structure and CoFeB composition dependence of perpendicular magnetic anisotropy employing Pt heavy metal layer

Pt is an expected heavy metal material for its large spin orbit coupling effect. However, Pt layer always display a different perpendicular magnetic anisotropy (PMA) influence tendency when it fabricated with the magnetic tunnel junction adopting material CoFeB. In this research, the properties of P...
