About Ge(Mn) diluted magnetic semiconductor
Deposition of 0.5 monolayer of Mn by molecular beam epitaxy on the surface of a Ge(0 0 1) substrate, and annealing, allowed the fabrication of a cluster-free Ge(Mn) diluted solution. Electronic spin resonance (ESR) was used to study the magnetic properties of this solution. These measurements, combined with secondary ion mass spectrometry, atomic force microscopy, and Auger electron spectroscop...
متن کاملMapping the magnetic anisotropy in (Ga,Mn)As nanostructures
Anisotropic strain relaxation in Ga,Mn As nanostructures was studied combining time-resolved Kerr microscopy and ferromagnetic resonance techniques. Local resonance measurements on individual narrow stripes patterned along various crystallographic directions reveal that the easy axis of the magnetization can be forced perpendicular to the strain relaxation direction. Spatially resolved measurem...
متن کاملSpin-reorientation magnetic transitions in Mn-doped SmFeO3
Spin reorientation is a magnetic phase transition in which rotation of the magnetization vector with respect to the crystallographic axes occurs upon a change in the temperature or magnetic field. For example, SmFeO3 shows a magnetization rotation from the c axis above 480 K to the a axis below 450 K, known as the Γ4 → Γ2 transition. This work reports the successful synthesis of the new single-...
متن کاملMagnetic exchange interactions in Mn doped ZnSnAs2 chalcopyrite
Accurate ab initio full-potential augmented plane wave (FP-LAPW) electronic calculations within generalized gradient approximation have been performed for Mn doped ZnSnAs2 chalcopyrites, focusing on their electronic and magnetic properties as a function of the geometry related to low Mn-impurity concentration and the spin magnetic alignment (i.e., ferromagnetic vs antiferromagnetic). As expecte...
متن کاملStructure and magnetic properties of Mn-doped ZnO thin films
We report the structure and magnetic properties of Zn1–xMnxO thin fi lms grown on Si(001) substrates by pulsed laser deposition. Structure and phase evolution with Mn doping has been studied using x-ray diffraction, electron diffraction, and high-resolution electron microscopy. The undoped and 1% Mn-doped ZnO fi lms are completely (001) oriented, and further Mn doping deteriorates the (001) ori...
