MEASUREMENT OF LOCAL FIELDS AT IMPURITY Fe$sup 57$ ATOMS USING THE MOSSBAUER EFFECT
The Mossbauer effect in Fe/sup 57/ was used to study the local fields in Fe, Co, Ni, and n-type Si. Sources were prepared by coating the metal (Fe, Co, Ni, or Si) with Co/sup 57/as such or as CoCl/sub 2/, and the absorber was either type 310 stainless steel (Cr--Ni, 25--20%) or potassium ferrocyanide. Data gave a magnetic field for Fe/sup 57/ of 3.3 x 10/sup 5/,3.1 x 10/sup 5/, 2.6 x 10/sup 5/, and 3 x 10/sup 4/ gauss in Fe/sup 57/ Co, Ni, and n-type Si, respectively. Line broadening was observed for the stainless steel absorber experiments over those in which both source and absorber were iron, and possible reasons for this broadening are given.The advantages of silicon as a source base for Fe/sup 57/ over the others due to the absence of sellabsorption are pointed out.
