High-field Knight shifts of impurity nuclei in ferromagnets using NMRON

Following an earlier proposal that meaningful Knight shift values for dilute impurities in ferromagnets may only be deduced from NMRON field shift measurements performed in large applied magnetic fields (Bapp>1T), an extensive literature search has been undertaken, to assess the effects of this proposal on over twenty years of field shift NMRON studies. This literature search ultimately reveals only four systems (<8% of studies) satisfying the above prerequisite. The dated systems are 60CoFe and 103mRhFe with non-zero Knight shift values of K=+1.5(0.4)% and K=-5.6(1.7)% respectively; and 54MnNi and 125SbFe with effectively zero Knight shifts.
