The nuclear magnetic resonance of Fe/sup 57/ was observed in iron specimens in the form of powders of various sizes, foils, and whiskers. It was found that the resonant frequency varies slightly among nominally pure iron specimens-taken from different sources, suggesting that it is somewhat sensitive to impurity content. Prestrain of the specimen has a marked effect, the resonance in cold-rolled foil being very broad and weak compared to that observed in annealed foils. Observations of nuclear magnetic resonance in iron whiskers oriented both axially and transversely in the rf coil offer interesting conflrmatlon of the domaln wall enhancement mechanism put forth by Gossard and Portis. The temperature dependence of the Fe/sup 57/ resonance was investigated in the range 77 deg to 785 deg K. (auth)
