Publikováno v: J. Appl. Phys. 115, 17C104 (2014)

We present a comprehensive structural characterization of ferromagnetic SiC single crystals induced by Ne ion irradiation. The ferromagnetism has been confirmed by electron spin resonance and possible transition metal impurities can be excluded to be

Publikováno v: Appl. Phys. Lett. 95, 192505 (2009)

Crystalline Mn5Ge3 nanomagnets are formed inside a Mn-diluted Ge matrix using Mn ion implantation. A temperature-dependent memory effect and slow magnetic relaxation are observed below the superparamagnetic blocking temperature of Mn5Ge3. Our finding

Report

Ferromagnetic, structurally disordered ZnO implanted with Co ions

Autor: Potzger, Kay, Zhou, Shengqiang, Xu, Qingyu, Shalimov, Artem, Groetzschel, Rainer, Schmidt, Heidemarie, Muecklich, Arndt, Helm, Manfred, Fassbender, Juergen

Publikováno v: Appl. Phys. Lett. 93, 232504 (2008)

We present superparamagnetic clusters of structurally highly disordered Co-Zn-O created by high fluence Co ion implantation into ZnO (0001) single crystals at low temperatures. This secondary phase cannot be detected by common x-ray diffraction but i
