Superconductivity in magnetically orderedCeTe1.82

We report the discovery of pressure-induced superconductivity in a semimetallic magnetic material ${\mathrm{CeTe}}_{1.82}.$ The superconducting transition temperature ${T}_{c}=2.7\mathrm{K}$ (well below the magnetic ordering temperatures) under pressure $(g2\mathrm{kbar})$ is remarkably high, considering the relatively low carrier density due to a charge-density-wave transition associated with lattice modulation. The mixed magnetic structure of antiferromagnetism coexisting with ferromagnetism can provide a clue for this high ${T}_{c}.$ We discuss a possible theoretical model for the superconducting pairing mechanism.
