Crystalline Ni nanoparticles as the origin of ferromagnetism in Ni implanted ZnO crystals

Shengqiang Zhou, K. Potzger, Gufei Zhang +4

We report the structural and magnetic properties of ZnO single crystals implanted at 623 K with up to 10 at. % of Ni. As revealed by X-ray diffraction, crystalline fcc-Ni nanoparti…
