Fe3Se4: A Possible Ferrimagnetic Half-Metal?
Girish C. Tewari, Divya Srivastava, Reijo Pohjonen +4
Half-metallic ferromagnets show 100% spin-polarization at the Fermi level and are ideal candidates for spintronic applications. Despite the extensive research in the field, very fe…
Observation of lattice softening at in the FeSeTe superconductor
J. Lindén, J. -P. Libäck, M. Karppinen +2
Polycrystalline samples of FeSeTe were synthesized using a conventional solid-state reaction method. The onset of bulk superconductivity transition was confirmed by…
Structural and magnetic properties of MSr2Y1.5Ce0.5Cu2Oz (M-1222) compounds with M = Fe and Co
V. P. S. Awana, Anurag Gupta, H. Kishan +5
MSr2Y1.5Ce0.5Cu2Oz (M-1222) compounds, with M = Fe and Co, have been synthesized through a solid-state reaction route. Both compounds crystallize in a tetragonal structure (space g…
Iron and molybdenum valences in double-perovskite (Sr,Nd)2FeMoO6: electron-doping effect
J. Linden, T. Shimada, T. Motohashi +2
Double perovskite, (Sr1-xNdx)2FeMoO6, was doped with electrons through partial substitution of divalent Sr by trivalent Nd (0 < x < 0.2). The Fe valence and the degree of B-site or…
The valence state of iron in the Sr2Fe(Mo,W,Ta)O6.0 double-perovskite system: An Fe K-edge and L2,3-edge XANES study
M. Karppinen, H. Yamauchi, Y. Yasukawa +4
Here we employ both Fe K and L2,3 edge x-ray absorption near-edge structure (XANES) spectroscopy techniques to clarify that iron in the B-site ordered double-perovskite halfmetal,…
Iron valence in double-perovskite (Ba,Sr,Ca)2FeMoO6: Isovalent substitution effect
Y. Yasukawa, M. Karppinen, J. Linden +3
In the Fe-Mo based B-site ordered double-perovskite, A2FeMoO6.0, with iron in the mixed-valence II/III state, the valence value of Fe is not precisely fixed at 2.5 but may be fine-…
