Interwoven atypical quantum states in CeLiBi
arXiv:2210.01031 · doi:10.1103/PhysRevB.106.214433
Abstract
We report the discovery of CeLiBi, the first example of a material in the tetragonal Ce ( = transition metal; = pnictogen) family wherein an alkali cation replaces the typical transition metal. Magnetic susceptibility and neutron powder diffraction measurements are consistent with a crystal-field ground state Kramers doublet that orders antiferromagnetically below K with an incommensurate propagation wave vector that generates a nanometric modulation of the magnetic structure. The best model of the ordered state is an elliptical cycloid with Ce moments primarily residing in the plane. This is highly unusual, as all other Ce members order ferromagnetically. Further, we observe an atypical hard-axis metamagnetic transition at T in magnetostriction, magnetization, and resistivity measurements. CeLiBi is a rare example of a highly conductive material with dominant skew scattering leading to a large anomalous Hall effect. Quantum oscillations with five frequencies arise in magnetostriction and magnetic susceptibility data to K and T, which indicate small Fermi pockets of light carriers with effective masses as low as 0.07. Density functional theory calculations indicate that square-net Dirac-like Bi bands are responsible for these ultralight carriers. Together, our results show that CeLiBi enables multiple atypical magnetic and electronic properties in a single clean material.
