WebAbstract The phosphorus NMR has been observed in the paramagnetic state of the metallic ferromagnet MnP. The phosphorus Knight shift was measured as a function of temperature and was found to be temperature-dependent and negative, varying from about -11% at 375°K to -2% at 575°K. WebThe OS is an "inverse KNIGHT shift" and it is an extremely sensitive way of measuring the KNIGHT shift and the NMR relaxation times, since the nuclei are dynamically polarized in these substances .

WebSep 10, 2010 · We report the results of Te/Se-nuclear magnetic resonance (NMR) measurements on Fe (Te 1- x Se x ). In the normal state, as the doping content of Te increases, both Knight shift and nuclear spin–lattice relaxation rate are enhanced in comparison with those for pure FeSe. Web27Al NMR Knight shifts as well as the spin-lattice relaxation rates in this compound. The Knight shift provides a local measurement of the susceptibility, which is less sensitive to the presence of impurities and other phases. The spin-lattice relaxation rate is sensitive to the excitation of quasiparticles around the Fermi level.
