Magnetic prop erties of the Cu-dop ed ZnO：exp eriments and theory
摘要
Abstract
CuxZn1-xO were synthesized via the solid-state reaction route. Ferromagnetism was detected when the Cu per-centage was bigger than 3%. The compounds were found to be the N-type semiconductors with a carrier concentration of 1015 cm-3. The DFT+U method was employed to calculate the magnetic exchange coupling of the Cu2+-O2--Cu2+, Cu2+-Vo-Cu2+, Cu2+-Vo+-Cu2+, Cu2+-Vo++-Cu2+ in the CuZnO system, where Vo denoted the vacancy of oxygen. Different bound charge transfer schemes between the Vo and Cu2+ ions were revealed. The origin of the ferromagnetism was determined within the framework of the Cu2+-Vo++-Cu2+ bound magnetic polarons.关键词
