Journal article (peer-reviewed)abstract
- We report on the effect of carbon implantation on the structural, electronic, and magnetic properties of Fe93Zr7 (FeZr) amorphous films. Extended X-ray absorption fine structure measurements on (FeZr)(100-x)C-x (x = 0, 5.5, and 11) indicate the incorporation of carbon in the FeZr matrix, with an increase of the Fe-Fe distance by implanting carbon. X-ray photoelectron spectroscopy measurements reveal the creation of Fe-C bonds after implantation. A significant enhancement of the Curie temperature and decrease of the coercivity are observed in the carbon-implanted films. Moreover, the non collinear ferromagnetism of the as-grown FeZr film diminishes upon carbon implantation.

Strain induced changes in magnetization of amorphous Co95Zr5 based multiferroic heterostructures
- 2013
-
In: AIP Advances. - : AIP Publishing. - 2158-3226. ; 3:2, s. 022113-
-
Journal article (peer-reviewed)abstract
- A clear change in the magnetic anisotropy in a layer of amorphous Co95Zr5 is obtained at the orthorhombic phase transition of the BaTiO3 substrate. The use of an amorphous buffer layer between the ferroelectric substrate and amorphous magnetic film shows that bulk strain governs the change in themagnetic anisotropy of our ferromagnetic-ferroelectric heterostructure. Moreover, we show that the thermal magnetization curves exhibit anisotropic behavior.

Tuning magnetic properties by hydrogen implantation in amorphous Fe100-xZrx thin films
- 2013
-
In: Journal of Magnetism and Magnetic Materials. - : Elsevier BV. - 0304-8853 .- 1873-4766. ; 346, s. 138-141
-
Journal article (peer-reviewed)abstract
- Thin films of amorphous Fe100-xZrx (x=7.6-12.9 at%) were synthesized by dc-magnetron sputtering. Samples with compositions of x=11.6 and 12.0 at% were hydrogenated by implantation. The Curie temperature increases with hydrogen content from 232 K for as-grown Fe88Zr12 to 370 K for a sample hydrogenated to 31 at%. The coercivity decreases dramatically upon hydrogenation, yielding films with tunable transition temperatures and soft magnetic properties.
