Hydrothermal Synthesis and Properties of Diluted Magnetic Semiconductor Zn1-xMnxO Nanowires
We report the synthesis of oriented single crystalline Mn doped ZnO nanowires through a hydrothermal method. Structural characterizations using X-ray diffraction and transmission electron microscopy revealed that the Mn was doped into the lattice structure, forming solid solution. The Mn doped ZnO nanowires possess wurtzite structure with a c-axis growth orientation. The physical properties of ...
متن کاملFerromagnetism in inhomogeneous Zn1−xCoxO thin films
We report on a systematic study of structural, optical, electrical, and magnetic properties of Zn1−xCoxO x=0.05–0.29 thin films codoped with Al 0.1% . Both codoped in which Co is cosputtered with other elements and -doped in which Co is doped digitally in the host matrix samples have been prepared and studied. Prior to doping of Co, growth conditions were optimized to produce ZnO:Al films with ...
متن کاملTheory of diluted magnetic semiconductor ferromagnetism
We present a theory of carrier-induced ferromagnetism in diluted magnetic semiconductors ( III1-xMnxV) which allows for arbitrary itinerant-carrier spin polarization and dynamic correlations. Both ingredients are essential in identifying the system's elementary excitations and describing their properties. We find a branch of collective modes, in addition to the spin waves and Stoner continuum w...
متن کاملAbout 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 کاملZnO-based nanostructures for diluted magnetic semiconductor
Since the prediction by Dietl et al. in the year 2000, extensive research activities have been focused on the ZnObased diluted magnetic materials (DMSs). Earlier works were mainly performed using bulk or thin film materials with transition-metal doping, and diverse magnetic properties including ferromagnetism, paramagnetism, and diamagnetism have been reported. Identifying the dominant mechanis...
