Abstract (AI)
This review focuses on the growth of high-quality (Li1−xFex)OHFeSe single crystals by a hydrothermal method using floating-zone-grown AxFe2−ySe2 (A = K, Rb, and Cs) as precursors. The structure, superconductivity, and magnetic behavior of the obtained crystals are highly influenced by the growth conditions, such as time, temperature, and composition. A phase diagram with temperature against the c-lattice constant is summarized including the antiferromagnetic spin density wave, superconducting, and paramagnetic phases.
Key Findings
1
A temperature–c-lattice-constant phase diagram summarizes antiferromagnetic spin-density-wave, superconducting, and paramagnetic phases.
2
Crystal structure, superconductivity, and magnetic behavior are strongly dependent on hydrothermal growth time, temperature, and composition.
3
High-quality (Li1−xFex)OHFeSe single crystals can be grown hydrothermally using floating-zone-grown AxFe2−ySe2 (A = K, Rb, Cs) precursors.
4
The review connects crystal-growth conditions and structural parameters with the resulting electromagnetic properties of (Li1−xFex)OHFeSe crystals.
