چکیده
Magnetic multilayers of (Ir/Co/Pt) 6 with interfacial Dzyaloshinskii-Moriya interaction (IDMI) were deposited by magnetron sputtering Co thickness d=1.8 nm. Exploiting magneto-optical Kerr effect in longitudinal mode microscopy, magnetic force and vibrating sample magnetometry, the field-driven evolution domain structures magnetization hysteresis loops have been studied. The existence weak stripe domains structure was deduced – tens micrometers size in-plane “core” modulated hundred nanometers out-of-plane magnetization. Micromagnetic simulations interpreted such distribution. Quantitative evaluation IDMI carried out using Brillouin light scattering (BLS) spectroscopy as difference between Stokes anti-Stokes peak frequencies Δ f. Due to additive nature IDMI, asymmetric combination Ir Pt covers led large values effective energy density D eff . It found that well f, measured a function applied field, show hysteresis. These results are explained under consideration influence on dynamics magnetized domains.

Dynamics of moisture interaction with polyelectrolyte multilayers containing nanofibrillated cellulose
Recent findings have shown that it is possible to use the Layer-by-Layer technique to create nanofibrillated cellulose / polyethyleneimine interference films whose colour change with relative humidity. This study uses different optical models to describe spectral ellipsometry measurements data of interference films and how the film properties alter in dry and humid environments. The results ind...
متن کاملNeural statics and dynamics
A formal theory of systems was proposed previously as providing a quantitative basis for neural computation. This theory dictated the architectural aspects of a pyramidal-neuron system model including its operation, adaptation, and most importantly, its computational objective. The principal result was a perceptron architecture that, through adaptation, learns to ask a specific space–time quest...
متن کاملChemical Statics and Dynamics
This is one of the text-books of Physical Chemistry edited by Sir Willam Ramsay. It views chemistry from the standpoint of the explanation of its phenomena by the physical laws which govern appreciable weights of substances, and it is shown that they operate equally in the changes which take place between individual mollecules during chemical reaction. It is pleasant to find that sharp distinct...
متن کاملComplex networks: Statics and Dynamics
We present some of the results obtained during the last 8 years about complex networks. Starting with the collection of data in the form of networks or graphs, we proceed on the characterization at different scales: microscopic, macroscopic, and mesoscopic. We introduce also the basic models incorporating complexity in the pattern of connectivities. Finally we review some results on dynamical f...
