摘要：

We investigate the structural and magnetic properties of Zn1xFex Te with an aim of discerning the intrinsic magnetism of this ternary compounds. Thin films of Zn1xFex Te with a high Fe composition up to x = 0.2 were grown by molecular beam epitaxy (MBE) in the excess of Te flux against Zn flux. The structural analyses using X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) measurements reveal that crystals of the pure diluted phase are grown at low Fe compositions less than x = 0.02, while precipitates of extrinsic phases start to be formed at higher Fe compositions. In the magnetization measurements, the films of x <= 0.02, which were confirmed to be of the pure diluted phase, exhibit paramagnetic behaviors down to 2 K. (C) 2014 WILEY-VCH Verlag GmbH & Co.
