Internal magnetic fields at Hg and TI in ferromagnets

Abstract

With the perturbed angular correlation method the hyperfine magnetic fields acting at 198Hg nuclei embedded in Fe, Co and Ni lattices are found to be -440 J: 105 kG, -370 :~ 78 kG and -86 J: 22 kG, respectively. The measured fields at 203T1 nuclei in Fe and Co lattices are -185 :e 70 kG and -90 ± 35 kG, respectively.
