Nano-scale, Ising-like Magnetic Domain Structures in Fe/NiO/Fe(100) Trilayers.

Oscillatory magnetic anisotropy in FeÕCrÕFe trilayers

We report our experimental finding that there exists an oscillation of magnetic anisotropy with varying Cr sublayer thickness along the direction normal to the easy axis in Fe/Cr/Fe trilayers, where the easy axis is induced along a certain direction in the film plane by applying an external field during film deposition. Interestingly enough, the squareness of the hysteresis loop measured along ...

Superhydrophobic micro/nano dual-scale structures.

In this paper, we present superhydrophobic micro/nano dual structures (MNDS). By KOH-etching of silicon, well-designed microstructures, including inverted pyramids and V-shape grooves, are first fabricated with certain geometry sizes. Nanostructures made of high-compact high-aspect-ratio nanopillars are then formed atop microstructures by an improved controllable deep reactive ion etching (DRIE...

Evolution of the Complexity of Magnetic Domain Structure in Nano-Scale Nickel Particles

The micromagnetic structure of nanofabricated nickel particles has been determined as a function of particle diameter and thickness using a combination of high-resolution magnetic force microscopy and LandauLifshitz-Gilbert micromagnetic simulations. Cylindrical particles were lithographically prepared with diameters in the range 68 900 nm, and thickness between 48 and 140 nm. Extensive measure...

Ising-like dynamics in large-scale functional brain networks.

Brain "rest" is defined--more or less unsuccessfully--as the state in which there is no explicit brain input or output. This work focuses on the question of whether such state can be comparable to any known dynamical state. For that purpose, correlation networks from human brain functional magnetic resonance imaging are contrasted with correlation networks extracted from numerical simulations o...
