Synthesis and magnetism of a Li2FeSiO4 single crystal
A macroscopic single crystal of γII-Li2FeSiO4 has been grown by means of the high-pressure optical floating-zone technique. Static magnetic susceptibility χ implies that the tetrahedrally-coordinated Fe2+ ions are in the high-spin, S=2, state. While a sharp decrease in χ implies long-range antiferro...

| Summary: | A macroscopic single crystal of γII-Li2FeSiO4 has been grown by means of the high-pressure optical floating-zone technique. Static magnetic susceptibility χ implies that the tetrahedrally-coordinated Fe2+ ions are in the high-spin, S=2, state. While a sharp decrease in χ implies long-range antiferromagnetic order below TN=17.0(5)K, the presence of a broad maximum at Tm=28K suggests quasi-low-dimensional magnetism. Applying magnetic fields along the easy magnetic a-axis yields additional contributions to the susceptibility ∂M/∂B and magnetostriction for B>7T, and an anomaly at B≈14.8T. |
