Bulk superconductivity in the kagome metal YRu 3 B 2
Abstract
Abstract Materials with a kagome lattice have been heavily studied for their exotic electronic band structure, geometrical frustration, high-temperature charge-order transitions, and unconventional electron-phonon coupling. In LaRu 3 Si 2 , it was proposed that electronic flat bands conspire with the characteristic phonon spectrum of the kagome lattice to drive enhanced superconductivity at T c = 6.8 K. Here, we report bulk superconductivity in the structural analogue YRu 3 B 2 , which hosts a pristine kagome lattice. We observe a superconducting transition at T c = 0.7 K through magnetization, resistivity, and heat-capacity measurements in this novel kagome metal.
