Low magnetic field magnetocaloric (MC) properties of La1 - xSrxCoO3 (x = 0.3 and 0.5) near phase transition from a ferromagnetic to a paramagnetic state were investigated. It is shown that the change of Sr content allows MC effect in La1 - xSrxCoO3 to be tunable, which is more practical for construction of MC refrigeration. MC properties of the x = 0.5 sample are significantly greater than that of the x = 0.3 one. Furthermore, the results show that MC properties of La1 - xSrxCoO3 samples are significantly larger, and comparable with some MC properties of many materials like Gd1 - xCaxBaCo2O5.5 and Ge0.95Mn0.05.
