Physics
Analysis of magnetic hyperfine interactions of Fe2+ in FeF2, Fe2+:MnF2 and Fe2+:ZnF2 yields a core polarization hyperfine field Hc = −514 ± 30 kOe and a value of (r−3)eff = 3.9 ± 0.04 au.

Physics
Iron-doped KMgF3 single crystals have been studied by Mössbauer spectroscopy of Fe57. Single lines due to Fe2+ and Fe3+ are observed at room temperature. For TK, the Fe2+ line splits into a quadrupole doublet with a splitting ΔEQ=0.44±0.02 mm/sec. Comparison with a random-strain model due to Ham yields a value of 120 cm-1 for the position of the first excited spin-orbit split level. Magnetic hyperfine structure in external magnetic fields at low temperature is observed and analysis yields a value of -495 ±30 kOe for the corepolarization hyperfine field …
