Abstract
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 in Fe2+ and a value of 4.1 a.u. for〈1/r3〉.
