Chromium substitution suppresses the charge density wave in ScV<sub>6</sub>Sn<sub>6</sub>

ORAL

Abstract

The diverse HfFe6Ge6-type compounds exhibit interesting magnetic and electronic properties arising from their transition metal kagome layers. For example, the vanadium kagome layers in ScV6Sn6 help support a charge density wave (CDW) below 92 K. [1] I grew and characterized single crystals of Sc(V1-xCrx)6Sn6 to investigate the impact of band filling on CDW formation. Temperature dependent physical properties reveal that chromium substitution suppresses the CDW. I will discuss the how this observation sheds light on the factors which govern CDW formation in kagome metals.
