Chemical shift of NMR in HgTe, CdTe and their alloys

Magneto-Josephson effects in junctions with Majorana bound states

“…This process can exist in various materials, as long as optical pumping introduces nonequilibrium electron spins, which preferentially flip nuclear spins and induce nuclear hyperpolarization via the Overhauser effect [30]. In ad- dition, an external magnetic field with strength b, applied parallel to the spin-orbit axis, will make the orientation angle of the hyperfine transverse field wind at a rate ω L = γb, where γ/2π ≈ −7.6 MHz/T for 199 Hg or γ/2π ≈ 13.5 MHz/T for 125 Te nuclei [31]. Moreover, the nuclear polarization can persist for long times, limited by the inhomogeneous nuclear transverse spin lifetime T * 2 ∼ 100 µs, which already suffices for hundreds of precession periods for b ∼ 0.1 Tesla.…”

77Se and125Te nuclear magnetic resonance investigations in II?VI and IV?VI compounds

“…The results of the chemical shift of this work differ somewhat from the values, which can be evaluated from [7] using TeC12 as reference. Such a scattering of experimental points is possible, because for the used samples the concentration of free electrons which may influence the lineposition [5] is unknown. It should be mentioned, that the authors, which observed the NMR signal of 125Te in the solid samples [5][6][7] did not observe the signal of the reference solution by themselves, but used the old gyromagnetic ratio of Reference23 or a theoretical reference.…”

“…But from all of these nuclei only a few NMR investigations with low signal-to-noise ratios are published for 113Cd (Ref. [3][4][5], 125Te (Ref. [5][6][7], 199Hg (Ref.…”

“…5,[8][9][10][11][12][13][14], as far as we know. Although difficulties arose from referencing, the chemical shifts of 125Te in IIb-tellurides measured by Willig and Sapoval [7] agree fairly well with theoretical predictions made by these authors using the formalism of Jameson and Gutowsky [15].…”

N.M.R. orbital shifts of 125Te in solids, dependence on ionicity and local structure

“…In the lack of an experimental reference we use a detailed theory of the C.S. in CdTe given elsewhere [12]. This calculation, together with the experimental frequency of CdTe, gives us a theoretical reference :…”
