We report a detailed study of steplike metamagnetic transitions in polycrystalline [Formula presented]. The steps have a sudden onset below a critical temperature, are extremely sharp (width [Formula presented]), and occur at critical fields which are linearly dependent on the absolute value of the cooling field in which the sample is prepared. Similar transitions are also observed at low temperature in non-Co doped manganites, including single crystal samples. These data show that the steps are an intrinsic property, qualitatively different from either previously observed higher temperature metamagnetic transitions in the manganites or metamagnetic transitions observed in other materials.
