Abstract

Considerable attention has been paid recently to FeTe2O5Cl due to reduced dimensionality and frustration in the magnetic subsystem, succession of phase transitions, and multiferroicity. The efforts to grow its selenite sibling resulted in the mixed halide compound Fe(Te1.5Se0.5)O5Cl, which was found crystallizing in a different structural type and possessing properties drastically different from those of a parent system. Its magnetic subsystem features weakly coupled Fe3+-Fe3+ dimers showing the regime of short-range correlations at TM∼70K and long-range order at TN=22K. In a magnetically ordered state, sizable spin-orbital interactions lead to a small canting of Fe3+ moments. Magnetic dipole-dipole interactions contribute significantly to the experimentally observed orientation of magnetization easy axis in the ac plane. The first principles calculations of leading exchange interactions were found in agreement with measurements of thermodynamic properties and Raman spectroscopy.
