ABSTRACT
It is shown that in-situ 166mHo ( I = 7) in a spherical single crystal of HoF3 can be used as sensitive internal thermometer to thermally detect NMR (NMR-TDNO) from the 100% abundant stable 165Ho ( I = 7/2) nuclei. In addition, new 166mHo NMRON results are reported. Both the 166mHo NMRON and 165Ho NMR-TDNO spectra show three distinct quadrupolar split sub-resonances, in zero applied field. The data is used to make estimates of the Ho magnetic moments and quadrupole parameters for the 166mHo and 166mHo sites.

    Peculiarities of quadrupolar relaxation in electrolyte solutions were established via comparison of the data obtained from proton and deuteron resonances. It has been shown that quadrupole coupling constants (QCC) of deuterons depend not only on internal electron structure of molecule or ion,...

    Nuclear magnetic resonance on oriented 175Hf in iron host has been measured. Samples of 175Hf Fe were made by recoil implantation of the precursor 175Ta isotope. The resonance frequency and the resonance line width have been determined to be 139.0 (1) MHz and FWHM = 2.7 (2) MHz, respectively, in...

    It is found that over a wide range of temperatures and magnetic fields even a small concentration of magnetic impurities in a sample leads to a T[sup -1] temperature dependence of the nuclear heat capacity. This effect is due to nuclear spin polarization by the magnetic impurities. The parameter...
