Nuclear magnetic resonance studies of 123Sb and 121Sb in the SbxTe1-x liquid alloy system are described. Interest is focussed on the concentration dependence of the Knight shift and the NMR linewidth. Measurements of the Knight shift and linewidth have been carried out over the entire concentration range at elevated temperatures (900-1100) K. Knight shifts of 123Sb and 121Sb, measured to high precision, show hyperfine structure anomaly. Both. Knight shift and linewidth show strong dependence on the alloy concentration and extreme behavior at the concentrations 40 at.% Sb and 50 at.% Sb. respectively. The experimental results are discussed in terms of modes concerning the electronic structure of liquid semiconductors.

Abstract91Zr-and 63Cu-NMR measurements of the amorphous alloys CuxZr100-x(40≦x≦60) are reported. By comparison of the experimental quadrupole disturbed spectra with simulated spectra of the amorphous alloys a short range order can be deduced, which is similar to the local lattice symmetry of the corresponding crystalline compounds. Furthermore the Knight shift of both nuclei in the alloys could be determined.

Nuclear magnetic resonance studies in single-crystal tin specimens have been done at liquid helium temperatures. The Knight shift has been studied as a function of crystal orientation in a constant magnetic field for different values of field and temperature. The anisotropy of the Knight shift has been observed directly for the first time. The linewidth of the resonance has also been studied and the results indicate a contribution to this from indirect exchange interactions. An attempt has been made to observe oscillations in the Knight shift as a function of magnetic field in both tin and aluminum single crystals. None have been detected but an upper limit to the effect has been set and this is compared with theoretical estimates.

AbstractThe Knight shift of the 51V resonance has been measured as a function of temperature in poly-crystalline V3Si and VSi2 samples. For the VaSi system the measurements have been extended to the temperature range from 400 K up to 1250 K, whereas for VSi2 the first NMR measurements at all have been carried out, covering the range 300 to 1250 K. The observed 51V Knight shift in VSi2 is negative (K51V (T=272 K) = -0.15%) and tends to zero with increasing temperature.

The 27Al and the 55Mn nuclear magnetic resonance powder pattern lineshapes have been obtained in icosahedral and decagonal (T phase) Al-Mn quasiperiodic crystals, and are compared to that of orthorhombic Al6Mn. The quasiperiodic crystals yield much broader spectra with little resolved structure. The quadrupole and Knight shift parameters for the 55Mn resonance in orthorhombic Al6Mn have been determined as |vQ| = 0.76 MHz,Kax = −2.7 × 10−4, Kiso = + 5 × 10−3. The results imply that Al6Mn and the quasiperiodic crystals have similar electronic and magnetic properties.
