| Popis: | A macroscopic single crystal of γ II -Li2FeSiO4 has been grown by means of the high-pressure optical floating-zone technique. Static magnetic susceptibility χ implies that the tetrahedrally-coordinated Fe 2 + ions are in the high-spin, S = 2 , state. While a sharp decrease in χ implies long-range antiferromagnetic order below T N = 17.0 ( 5 ) K , the presence of a broad maximum at T m = 28 K 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 > 7 T , and an anomaly at B ≈ 14.8 T . |
