Magnetic properties of La1-xSrxCoO3 (0 less-than-or-equal-to x less-than-or-equal-to 0.5) have been studied by magnetization measurements in low magnetic fields. It has been found that there exist spin-glass (0 < x less-than-or-similar-to 0.18) and cluster-glass (0.18 less-than-or-similar-to x less-than-or-equal-to 0.5) regions. Ferromagnetic long-range order previously reported does not take place. Spin-glass behavior is ascribed to the frustration of random competing exchange interactions, namely the ferromagnetic double-exchange interaction between Co3+ and Co4+ and the antiferromagnetic one between like spins.
