Magnetic remanent states in antiferromagnetically coupled multilayers

open access: yes, 2008
In antiferromagnetically coupled multilayers with perpendicular anisotropy unusual multidomain textures can be stabilized due to a close competition between long-range demagnetization fields and short-range interlayer exchange coupling.

Organic-Inorganic Hybrid Planarization and Water Vapor Barrier Coatings on Cellulose Nanofibrils Substrates

open access: yesFrontiers in Chemistry, 2018
Cellulose nanofibrils (CNF) can be produced in the form of thin, transparent and flexible films. However, the permeability of such materials to oxygen and water vapor is very sensitive to moisture, which limits their potential for a variety of packaging ...

Theory of rigid-plane phonon modes in layered crystals

open access: yes, 2011
The lattice dynamics of low-frequency rigid-plane modes in metallic (graphene multilayers, GML) and in insulating (hexagonal boron-nitride multilayers, BNML) layered crystals is investigated. The frequencies of shearing and compression (stretching) modes

Spectral and polarization effects in deterministically nonperiodic multilayers containing optically anisotropic and gyrotropic materials [PDF]

open access: yes, 2006
Influence of material anisotropy and gyrotropy on optical properties of fractal multilayer nanostructures is theoretically investigated. Gyrotropy is found to uniformly rotate the output polarization for bi-isotropic multilayers of arbitrary geometrical ...

An innovative approach to partial discharge measurement and analysis in DC insulation systems during voltage transient and in steady state

open access: yesHigh Voltage, 2021
Measuring partial discharges in DC insulation systems is an issue due to the lack of a reference relating the voltage waveform to the physics of discharge phenomena.

Direct Probing of 1/f Noise Origin with Graphene Multilayers: Surface vs. Volume

open access: yes, 2012
Low-frequency noise with the spectral density S(f)~1/f^g (f is the frequency and g~1) is a ubiquitous phenomenon, which hampers operation of many devices and circuits. A long-standing question of particular importance for electronics is whether 1/f noise

Terahertz band communication using plasma wave propagation in multilayer graphene heterostructures

open access: yesIET Cyber-Physical Systems, 2018
Graphene-based heterostructures provide a viable platform to implement optoelectronic devices that can operate in the terahertz (THz) band. In this study, the authors focus on multilayer (ML) graphene as the building block to implement high-frequency and

Local sublattice-symmetry breaking in rotationally faulted multilayer graphene

open access: yes, 2010
Interlayer coupling in rotationally faulted graphene multilayers breaks the local sublattice-symmetry of the individual layers. We present a theory of this mechanism, which reduces to an effective Dirac model with space-dependent mass in an important ...

Microstructure formation in electrodeposited Co-Cu/Cu multilayers with GMR effect: influence of current density during the magnetic layer deposition [PDF]

open access: yes, 2011
The influence of the current density applied during the deposition of the magnetic layers on the microstructure formation in electrodeposited Co-Cu/Cu multilayers and on their giant magnetoresistance (GMR) was investigated using a combination of ...
