Abstract The effect of hydrostatic pressure on the superconductivity of La1.2−x Eu x Mo6S8 pseudoternary compounds was studied by means of low-frequency ac and dc magnetic susceptibility measurements up to 20 kbar. The superconducting transition temperatureT c at ambient pressure is a weak function of Eu concentrationx for 0≲x≲0.2, and then decreases smoothly withx forx〉0.2 until superconductivity is completely suppressed forx≥0.95. Pressure was found to decreaseT c in the La-rich compounds and to increaseT c in the Eu-rich compounds. Pressure also induces superconductivity in compounds withx〉0.95 that are not superconducting at ambient pressure. A La0.2Eu1.0Mo6S8 compound revealed a sizeable Meissner effect for pressures larger than 7 kbar.
