Synthesis and Crystal Growth of Tetragonal Fe1.00Se

Abstract

Single crystals of tetragonal Fe1.00Se were grown from polycrystalline material by chemical vapor transport reaction at temperatures below 723 K using AlCl3 as transport additive. The plate-shaped single crystals have edge lengths up to 4 mm. The single crystals display complete diamagnetic shielding factor 4piX = -1 below the superconducting transition.
