We report the discovery of pressure-induced superconductivity in a semimetallic magnetic material CeTe 1.82 . The superconducting transition temperature T c ϭ2.7 K ͑well below the magnetic ordering tempera-tures͒ under pressure (Ͼ2 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.
