Abstract
The FeSe0.94 single crystals have been grown using the high-temperature KCl flux technique. The size of crystal is up to 4 × 3 × 0.1 mm3 dimension. The phase of crystal sample has been identified by powder x-ray diffraction, including dominant tetragonal phase and trace amounts of hexagonal phase. Energy-dispersive spectroscopy reveals the sample composition. With the resistance measurements, the superconducting transition temperature Tc ~ 9.5 K is obtained. Magnetization measurement is presented, which indicates the coexistence of superconductivity and weak ferromagnetism below Tc. The structure transition appears at around 90 K, determined by the temperature derivative of the resistance dR/dT.
