M.A. Kuznetsov, O.G.Udalov, A.A.Fraerman
TL;DR
This paper analyzes the anisotropic nature of the magnetostatic 'orange-peel' coupling in magnetic multilayers, revealing how the interaction varies with magnetization orientation and offering a method to distinguish it from exchange coupling.
Contribution
It provides a theoretical calculation of the anisotropic 'orange-peel' coupling energy in magnetic multilayers with correlated interfaces.
Findings
The coupling is ferromagnetic for in-plane magnetization.
The coupling is antiferromagnetic for out-of-plane magnetization.
The anisotropy helps differentiate 'orange-peel' from exchange coupling.
Abstract
We calculate the energy of the magnetostatic interaction between two ferromagnetic films with uniform magnetization and correlated interfaces (the "orange-peel" effect). The "orange-peel" coupling is anisotropic: the interaction is ferromagnetic when the films are magnetized in-plane; and it is antiferromagnetic when magnetization is out-of-plane. The interaction anisotropy can be used to distinguish the "orange-peel" effect from the interlayer exchange coupling.
