Magnetization reversal in cobalt antidot arrays

We have carried out a detailed study of the magnetic switching in square lattice cobalt antidot arrays with periods ranging from 2 m down to 200 nm antidot size=antidot separation . Magneto-optical Kerr effect measurements show first a small change in the magnetization due to a reversible rotation of the magnetic spins in the antidot rows, followed by a large change due to reversal of the antid...

Neural Network Analysis of the Magnetization Reversal in Magnetic Dot Arrays

We simulated the remagnetization dynamics of the ultra-dense and ultra-thin magnetic dot array system with dipole-dipole and exchange coupling interactions. Within the proposed 2D XY superlattice model, the square dots are modeled by the spatially modulated exchange-couplings. The dipole-dipole interactions were approximated by the hierarchical sums and dynamics was reduced to damping term of t...

Magnetization reversal and microstructure in polycrystalline Fe50Pd50 dot arrays by self-assembling of polystyrene nanospheres

Nanoscale magnetic materials are the basis of emerging technologies to develop novel magnetoelectronic devices. Self-assembly of polystyrene nanospheres is here used to generate 2D hexagonal dot arrays on Fe50Pd50 thin films. This simple technique allows a wide-area patterning of a magnetic thin film. The role of disorder on functional magnetic properties with respect to conventional lithograph...

Studies of the Magnetization Reversal Processes in Co Dot and Antidot Arrays on a Microscopic Scale

Co dot and antidot arrays with hexagonal symmetry have been prepared by combined electrochemical and sputtering techniques with significantly reduced nanoscale dimensions. Their magnetization reversal process has been analyzed on a macroscopic scale with Vibrating Sample Magnetometry (VSM) and on a microscopic scale by high spatial resolution Magnetic Transmission Soft X-ray Microscopy (MTXM). ...

Angular dependence of magnetization reversal process in exchange biased epitaxial MnPd/Fe bilayers

We investigated the angular dependence of magnetization reversal in epitaxial MnPd/Fe bilayers grown on MgO 001 using combined longitudinal and transverse magneto-optical Kerr effect. Square loops, asymmetrically shaped loops, and double-shifted loops were observed as the field orientation was varied from parallel to perpendicular to the bias direction. Additionally, including the effect of an ...
