Mössbauer Spectroscopy Study Of The Spin‐Flop Transition In Fe‐Doped Mnf2, C. R. Abeledo, Richard B. Frankel, A. Misetich, N. A. Blum Mar 1971

Mössbauer Spectroscopy Study Of The Spin‐Flop Transition In Fe‐Doped Mnf2, C. R. Abeledo, Richard B. Frankel, A. Misetich, N. A. Blum

Physics

Measurements of the hyperfine interaction in Fe+ + in MnF2 in external fields above the spin‐flop field at 4.2 K are reported and a value of g⊥ = 2.13 is derived, in good agreement with theory.

Mössbauer Effect In Fe-Doped Kmgf3, J. Chappert, J. R. Regnard, Richard B. Frankel, A. Misetich, N. A. Blum Mar 1971

Mössbauer Effect In Fe-Doped Kmgf3, J. Chappert, J. R. Regnard, Richard B. Frankel, A. Misetich, N. A. Blum

Physics

An iron-doped KMgF3 single crystal has been studied with the Mössbauer technique. The two charge states, Fe2+ and Fe3+, are observed. Below 12 °K an Fe2+ quadrupole doublet appears. Using Ham strain model we calculate that the first excited spin-orbit level lies ~ 120 cm-1 above the Γ5g ground state.

Mossbauer Study Of An Intramolecular Antiferromagnet, R. Lechan, C. R. Abeledo, R. B. Frankel Jan 1971

Mossbauer Study Of An Intramolecular Antiferromagnet, R. Lechan, C. R. Abeledo, R. B. Frankel

Physics

Mossbauer measurements at 4.2 ≤T ≤ 22 K and OsHosBO kOe are + reported in (Fe Salen Cl)2, a molecular complex containing two coupled Fe3+ ions bridged by oxygen atoms. At 4.2 K only the ground state with effective spin S = 0 is appreciably populated. Analysis of the magnetic field and temperature dependence of the magnetic hyperfine field yields an exchange constant J= -6.7 cm>sup>-1 and a hyperfine field of -192 kOe per unit spin at each Fe3+ nucleus.
