Spin wave modes of multilayered ferromagnetic films
(American Physical Society, 2019)
© 2019 American Physical Society.A study of ferromagnetic spin wave modes in multilayered films under general conditions is presented within a micromagnetic approximation. These modes, either in the magnetostatic or ...
The damping of spin motions in ultrathin films: Is the Landau-Lifschitz-Gilbert phenomenology applicable?
(ELSEVIER, 2006-10-01)
The Landau-Lifschitz-Gilbert (LLG) equation is used widely in device design to describe spin motions in magnetic nanoscale structures. The damping term in this equation plays an essential role in the description of the ...
Instabilities of spin torque driven auto-oscillations of a ferromagnetic disk magnetized in plane
(Amer Physical Soc., 2016)
The stability of the magnetization auto-oscillations of the ferromagnetic free layer of a cylindrical nanopillar structure is studied theoretically using a classical Hamiltonian formalism for weakly interacting nonlinear ...
Nonlinear nano-scale localized breather modes in a discrete weak ferromagnetic spin lattice
(Elsevier, 2016)
We investigate the propagation dynamics of highly localized discrete breather modes in a weak ferromagnetic spin lattice with on-site easy axis anisotropy due to crystal field effect. We derive the discrete nonlinear ...
Coupling between an incommensurate antiferromagnetic structure and a soft ferromagnet in the archetype multiferroic BiFeO3/cobalt system
(Amer Physical Soc, 2015)
Multiferroic materials are mostly antiferromagnets, often containing incommensurate magnetic arrangements stemming from the magnetoelectric interaction. Using soft x-ray resonant magnetic scattering, we show that these ...
Enhanced positive and negative exchange bias in FeF2/Ni with dusted interfaces
(American Institute of Physics, 2020)
An enhanced exchange bias was found in FeF2/Ni interfaces by inserting dusting of Pd and Cu atoms. We have used an ultrathin wedge to investigate systematically the effect of a discontinuous nonmagnetic spacer between the ...
Structural, morphological, optical and magnetic properties of Ag3(2+x)InxNb4-xO11+delta (0.25 ≤ x ≤ 1.0) nanoparticles synthesized by sol-gel method
(Elsevier, 2018-09)
Herein, we report the structure, morphology, optical and magnetic properties of novel Ag3(2+x) InxNb4-xO11+delta (0.25 <= x <= 1.0; Al-A4) nanoparticles prepared by sol-gel technique. The samples were studied using X-ray ...
Dipolar-driven formation of cobalt nanoparticle chains in polyethylene films
(Elsevier, 2015)
Using a simple method we produce polyethylene film with embedded chains of cobalt nanoparticles. The crystalline magnetic nanoparticles were synthesized through a simple chemical reduction method at room temperature using ...
Composition-dependent structural, electrical, magnetic and magnetoelectric properties of (1-x)BaTiO3-xCoFe(2)O(4)particulate composites
(Indian Acad Sciences, 2020)
Multiferroic composite with the general formula (1 - x)BaTiO3-xCoFe(2)O(4)(x= 0.05, 0.15, 0.25, 0.35 and 0.45) has been synthesized by a standard solid-state reaction route. Powder X-ray diffraction analysis confirms the ...
