摘要
To understand the intrinsic magnetic nature of ZnMnO thin films without the influence of the clustering and segregating Mn ions due to the formation of misfit dislocations and staking faults, ZnO films with the Mn concentration up to 10 at% were prepared on (000 1) ZnO single-crystal substrate by pulsed laser deposition (PLD) method. The lattice constant along the c-axis of the ZnMnO films linearly increases with increasing the Mn concentration, and that along a-axis does not change from that of ZnO substrate showing the pseudomorphic growth of the ZnMnO films. The intrinsic magnetization behavior could be obtained by using these ZnMnO films. The ZnMnO films up to 10 at% Mn exhibit typical paramagnetic nature at 1.85K including the antiferromagnetic interaction of Mn-O-Mn superexchange. (C) 2006 Elsevier B.V. All rights reserved.
