Isolated spin ladders in Ln${}_2$Ti${}_9$Sb${}_{11}$ (Ln:La-Nd) metals

Brenden R. Ortiz, Heda Zhang, Karolina Gornicka +4

Here we present the discovery and characterization of a series of antimonides Ln${}_2$Ti${}_9$Sb${}_{11}$ (Ln: La--Nd) which exhibit well-isolated, $n=2$ rare-earth spin ladders. We disc…
