X-ray magnetic circular dichroism in (Ge,Mn) compounds: experiments and modeling
Samuel Tardif, Andrey Titov, Emmanuel Arras +10
X-ray absorption (XAS) and x-ray magnetic circular dichroism (XMCD) spectra at the L edges of Mn in (Ge,Mn) compounds have been measured and are compared to the results of…
Exchange bias in GeMn nanocolumns: the role of surface oxidation
S. Tardif, S. Cherifi, M. Jamet +9
We report on the exchange biasing of self-assembled ferromagnetic GeMn nanocolumns by GeMn-oxide caps. The x-ray absorption spectroscopy analysis of this surface oxide shows a mult…
Imaging ferroelectric domains in multiferroics using a low-energy electron microscope in the mirror operation mode
Salia Cherifi, Riccardo Hertel, Stéphane Fusil +5
We report on low-energy electron microscopy imaging of ferroelectric domains with submicron resolution. Periodic strips of 'up' and 'down'-polarized ferroelectric domains in bismut…
From diluted magnetic semiconductors to self-organized nanocolumns of GeMn in Germanium
Samuel Tardif, Ing-Song Yu, Thibault Devillers +6
While achieving high Curie temperatures (above room temperature) in diluted magnetic semiconductors remains a challenge in the case of well controlled homogeneous alloys, several s…
Magnetostructure of MnAs on GaAs revisited
Ernst Bauer, Rachid Belkhou, Salia Cherifi +3
The ferromagnetic to nonferromagnetic (α-β) phase transition in epitaxial MnAs layers on GaAs(100) is studied by x-ray magnetic circular dichroism and x-ray magnetic line…
Tuning the domain wall orientation in thin magnetic strips by induced anisotropy
S. Cherifi, R. Hertel, A. Locatelli +5
We report on a method to tune the orientation of in-plane magnetic domains and domain walls in thin ferromagnetic strips by manipulating the magnetic anisotropy. Uniaxial in-plane…
