The temperature dependences M(T) and field dependences M(H) of the magnetization have been measured in single-crystal TbBaCo4O7 for two magnetic-field directions: H vertical bar vertical bar c and H perpendicular to c. In the case of H vertical bar vertical bar c, a magnetic field-induced irreversible transition is detected at low temperatures, accompanied by magnetization jumps on the M(H) dependences. It is shown that the transition field depends on the rate at which the external magnetic field is introduced.
