Magnetic measurements were carried out on La0.9Ca0.1CoO3 single crystals. In the absence of applied magnetic field, this compound is an insulator down to 4.2 K. Results of magnetization measurements suggest a spin glass ground state. An applied field of 5T drives the insulator ground state to a ferromagnetic metallic state. This field induces antiferromagnetic low spin/spin-glass-like mixed spin transition. The energy gap for ls/hs transition was estimated to be 0.12 meV.
