We discuss the surface-induced low-field instability of the antiferromagnetic phase of magnetic multilayers. The threshold field is calculated analytically for multilayers of arbitrary thickness containing an even number of ...

Nonuniform canting states are found for multilayers of a finite size that are constructed from ferromagnetic films which are antiferromagnetically coupled. Our results are applicable to a wide variety of experimentally ...

Epitaxial ZnFe2O4 thin films were deposited on monocrystalline MgO substrate by dc-sputtering. Ferrites were grown from Zn-O and Fe-O multilayers starting from metallic targets in oxygen atmosphere. The number and thickness ...

Exchange coupling between magnetic films can lead to an attractive force between domain walls in the separate films. The coupling between the films allows for small amplitude oscillations around the equilibrium configuration ...

Spin-wave-based circuits and logic devices have been considered as an alternative to current electronic devices as they approach the physical limit of miniaturization. Asymmetrical propagation of spin waves, also known as ...

The perpendicular exchange bias and magnetic anisotropy were investigated in IrMn/Pt/[Co/Pt](3) multilayers through the analysis of in-plane and out-of-plane magnetization hysteresis loops. A phenomenological model was ...

The present work investigates the structural and magnetic properties of ZnFe2O4 thin films obtained  from ZnO/FeO multilayers deposited on MgO substrate by DC reactive sputtering. We show that this  method is good to grow ...

Granular magnetic systems can be composed by magnetic particles or clusters with size of some nanometers. These magnetic nanoparticles present different magnetic order phases, as superparamagnetic, and they can be embedded ...

This thesis describes three experiments in the topics of magnetism and superconductivity. The first experiment demonstrates the ability to have magnetic control of the triplet component amplitude in a Nb/Co/Cu/Co/CoO ...
