Morphology and magnetic properties of Fe3O4 nanodot arrays using template-assisted epitaxial growth
Arrays of epitaxial Fe3O4 nanodots were prepared using laser molecular beam epitaxy (LMBE), with the aid of ultrathin porous anodized aluminum templates. An Fe3O4 film was also prepared using LMBE. Atomic force microscopy and scanning electron microscopy images showed that the Fe3O4 nanodots existed over large areas of well-ordered hexagonal arrays with dot diameters (D) of 40, 70, and 140 nm; ...
متن کاملCoherent magnetic semiconductor nanodot arrays
In searching appropriate candidates of magnetic semiconductors compatible with mainstream Si technology for future spintronic devices, extensive attention has been focused on Mn-doped Ge magnetic semiconductors. Up to now, lack of reliable methods to obtain high-quality MnGe nanostructures with a desired shape and a good controllability has been a barrier to make these materials practically app...

15 صفحه اولRemanence and switching sensitivity in nanodot magnetic arrays.
New results are reported of the computer simulations on the magnetic behaviour of magnetic arrays of nanoscopic dots, placed in cells of the square lattice. We show that the remanence magnetization M(r) decreases with the array size. For arrays 50 x 50, we investigate also the stability of the magnetic structure of an array in an oscillating magnetic field. The damage spreading technique reveal...
متن کاملSelf-assembly and optical properties of patterned ZnO nanodot arrays
Patterned ZnO nanodot (ND) arrays and a ND-cavity microstructure were realized on an anodic alumina membrane (AAM) surface through a spin-coating sol–gel process, which benefits from the morphology and localized negative charge surface of AAM as well as the optimized sol concentration. The growth mechanism is believed to be a self-assembly process. This provides a simple approach to fabricate s...
