Extremely large magnetoresistance in an unfilled skutterudite quadratic contact point semimetal CoP3

Extremely large magnetoresistance (EXMR) and high mobility are always desired for use in spintronic devices. Herein, we report the observation of EXMR and very large hole mobility reaching ∼ 2 × 104% (30 T) and ∼2 × 104 cm2 V−1 s−1, respectively, at 2 K in an unfilled skutterudite CoP3 crystal. The magnetotransport measurements unveil remarkable Shubnikov–de Haas quantum oscillations hosting nontrivial Berry phase induced by strong Zeeman splitting. First-principles calculations suggest band inversion between Co-dxy/yz and P-pz orbitals, which forms fourfold quadratic contact point at the Γ point above the Fermi level of ∼0.146 eV. The angle-resolved photoelectron spectroscopy measurements verify the calculated surface state. The results provide a quadratic contact point semimetal, which has potential applications in topological devices.
