Abstract
We present magnetic properties of Zn(Mn,âP)O thin films, with 5 at% Mn, epitaxially grown by pulsed laser deposition in oxygen atmosphere on a-plane sapphire substrates. Ferromagnetism above room temperature was obtained for films with 0.1 at% P, grown at around 600â°C. Temperature-dependent magnetization curves indicate the presence of an antiferromagnetic coupling between the Mn magnetic moments. After annealing ferromagnetic films for 2 hours at 800â°C in N2 atmosphere, they became paramagnetic at all temperatures.
