Crystal growth and magnetic properties of a kagomé compound Cs2NaMn3F12

Cs2NaMn3F12, one of manganese based fluorides A2A′Mn3F12 (A = Rb, Cs; A′ = Li, Na, K), has been found to exhibit a typical kagomé structure. Here, we report the first successful growth of large-sized single crystals of Cs2NaMn3F12 by means of a hydrothermal method. Good quality of grown crystals is confirmed by the XRD and EDS techniques. Magnetic measurements suggest that Cs2NaMn3F12 possesses an antiferromagnetic ordering at 2.5 K and a remarkably geometrical frustration effect in the system.
