Domain state susceptibility in FeCl2/CoPt-heterostructures

Magnetic CoPt Nanoparticles Deposition using Plasma Focus Device

A 3.3 kJ pulsed plasma focus device (NX2) was used to deposit magnetic CoPt nano-particles on Si (100) substrates at a low charging voltage of about 8kv. The hydrogen was used as filling gas at different gas pressures (2, 4, 6, and 8 mbar) to investigate the morphological, structural and magnetic properties of nanostructure thin films, using scanning electron microscopy (SEM), X-ray diffraction...

Exchange Bias in FeF20-CoPt heterosystems with perpendicular anisotropy

The exchange bias e!ect is measured in heterosystems with perpendicular anisotropy consisting of Co/Pt multilayers on top of the (0 0 1) face of a FeF single crystal. The resulting exchange "eld H exhibits a strong dependence on temperature and the axial freezing "eld, H . Within the framework of an Ising-type model, the H vs. 1 as well as the H vs.H data are explained in terms of the microscop...

STEM nanodiffraction technique for structural analysis of CoPt nanoparticles.

Studying the structure of nanoparticles as a function of their size requires a correlation between the image and the diffraction pattern of single nanoparticles. Nanobeam diffraction technique is generally used but requires long and tedious TEM investigations, particularly when nanoparticles are randomly oriented on an amorphous substrate. We bring a new development to this structural study by ...
