Title: HYPERFINE STRUCTURE OF Fe$sup 57$ IN PARAMAGNETIC AND ANTIFERROMAGNETIC FeF$sub 2$ FROM THE MOSSBAUER EFFECT

Abstract

Measurements of the gamma resonant absorption in oriented slabs of FeF/ sub 2/ were used to determine the magnitude and direction of the magnetic field at the iron nucleus in the antiferromagnetic state (3.40 x lO/sup 5/ oe at 0 deg K) and the quadrupole splitting in the paramagnetic state (31.2 Mc/sec) of this material. The observed electric and magnetic hfs in the antiferromagnetic state is interpretable in terms of an asymmetric electric field gradient tensor with its major axis perpendicular to the c axis, an asymmetry parameter of 0.33, and a quadrupole splitting of 30.3 Mc/sec at 45 deg K.
