Carrier induced ferromagnetism in Nb doped Co:TiO2 and Fe:TiO2 epitaxial thin film
We have investigated the carrier induced magnetic properties of anatase Ti1–x–yNbxMyO2 (M=Co,Fe) epitaxial films grown by the pulsed laser deposition technique. For Ti0.95–xNbxCo0.05O2,...

The nearest-neighbor magnetic exchange interactions in Zn0.95Mn0.05O, Zn0.95Co0.05O, and Zn0.98Mn0.02Te were investigated by measuring inelastic neutron scattering from isolated exchange-coupled spin-spin pairs. The experiments on Zn0.98Mn0.02Te were carried out at atmospheric pressure and then at 4  kbar pressure in order to determine the dependence of the exchange parameter on the spin-spin distance. ©2006 American Institute of Physics
