A study was conducted to analyze longitudinal spin-density-wave ordering in thin epitaxial chromium layers. nuclear method based on the hyperfine interaction was utilized to characterize the magnetism in the samples. Experimental results indicated that the spin-flip transition in chromium as an anisotropy influences rather than an intrinsic characteristics of the spin-density-wave ordering.

We present a lattice location study of the n-type dopant arsenic after ion implantation into germanium. By means of electron emission channeling experiments, we have observed that the implanted As atoms substitute the Ge host atoms and that, in contrast to several implanted metal impurities in Ge, no significant fraction of As is found on interstitial sites. The substitutional As impurities are found to be thermally stable up to 600 °C. After 700 °C annealing a strong reduction of emission channeling effects was observed, in full accordance with the expected diffusion-induced broadening of the As profile. [ABSTRACT FROM AUTHOR]
