Collapse of the standard ferromagnetic domain structure in hybrid Co/Molecule bilayers Open
We show that, upon the chemisorption of organic molecules, Co thin films display a number of unique magnetic properties, including the giant magnetic hardening and the violation of the Rayleigh law in magnetization reversal. These novel pr…

The Ferromagnetic Glass State: collapse of the standard ferromagnetic domain structure Open
We demonstrate that, upon the chemisorption of organic molecules, Co thin films display a novel magnetic phase that we tentatively call Ferromagnetic Glass State. This is characterised by a giant magnetic hardening and by the violation of …

The Dynamics of Domain Wall Motion in Spintronics Open
A general equation describing the motion of domain walls in a magnetic thin film in the presence of an external magnetic field has been reported in this paper. The equation includes all the contributions from the effects of domain wall ine…

Stripe domains reorientation in ferromagnetic films with perpendicular magnetic anisotropy Open
Ferromagnetic thin films with moderate perpendicular magnetic anisotropy (PMA) are known to support weak stripe domains provided film thickness exceeds a critical value. In this work, we performed both an experimental and theoretical inves…

Robustness of majority gates based on nanomagnet logic Open
We studied the evolution of the magnetic state of a majority logic gate consisting of a cluster of five dipolarly-coupled nanomagnets, fabricated by e-beam lithography, under the application of a clocking field, using a combination of magn…

Perpendicular Magnetic Anisotropy in Fe–N Thin Films: Threshold Field for Irreversible Magnetic Stripe Domain Rotation Open
The magnetic properties of an iron nitride thin film obtained by ion implantation have been investigated. N[Formula: see text] ions were implanted in a pristine iron layer epitaxially grown on ZnSe/GaAs(001). X-ray diffraction measurements…

Exchange bias properties of 140 nm-sized dipolarly interacting circular dots with ultrafine IrMn and NiFe layers Open
We studied the exchange bias effect in an array of IrMn(3nm)/NiFe(3nm) circular dots(size 140nm and center-to-center distance 200nm,as revealed by microscopy analyses),prepared on a large area (3x3 mm2) by electron beam lithography and lif…
