The kagomé metals RbTi3Bi5 and CsTi3Bi5
Abstract
<jats:title>Abstract</jats:title><jats:p>The kagomé metals RbTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub> and CsTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub> were synthesized both as polycrystalline powders by heating the elements in an argon atmosphere and as single crystals grown using a self-flux method. The compounds crystallize in the hexagonal crystal system isotypically to KV<jats:sub>3</jats:sub>Sb<jats:sub>5</jats:sub> (<jats:italic>P</jats:italic>6/<jats:italic>mmm</jats:italic>, <jats:italic>Z</jats:italic> = 1, CsTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub>: <jats:italic>a</jats:italic> = 5.7873(1), <jats:italic>c</jats:italic> = 9.2062(1) Å; RbTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub>: <jats:italic>a</jats:italic> = 5.773(1), <jats:italic>c</jats:italic> = 9.065(1) Å). The titanium atoms form a kagomé net with bismuth atoms in the hexagons as well as above and below the triangles. The alkali metal atoms are coordinated by 12 bismuth atoms and form AlB<jats:sub>2</jats:sub>-like slabs between the kagomé layers. Magnetic susceptibility measurements with CsTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub> and RbTi<jats:sub>3</jats:sub>Bi<jats:sub>5</jats:sub> single crystals reveal Pauli-paramagnetism and traces of superconductivity caused by CsBi<jats:sub>2</jats:sub>/RbBi<jats:sub>2</jats:sub> impurities. Magnetotransport measurements reveal conventional Fermi liquid behavior and quantum oscillations indicative of a single dominant orbit at low temperature. DFT calculations show the characteristic metallic kagomé band structure similar to that of CsV<jats:sub>3</jats:sub>Sb<jats:sub>5</jats:sub> with reduced band filling. A symmetry analysis of the band structure does not reveal an obvious and unique signature of a nontrivial topology.</jats:p>
