We have demonstrated the effect of pressure on magnetization jump and its associated magnetostriction in Eu0.58Sr0.42MnO3. The critical field lowered by the applied pressure is explained by a suppression of the metastable blocked state, which is inherent to the phase separated manganite system exhibiting the magnetic avalanche. To reduce a factor of the bad thermal coupling in the bulk sample, and to further examine the nature of the magnetization jump, we have performed the influence of pressure on the isothermal magnetization of the powder sample. There is no discrepancy in the critical field between the bulk and powder samples although the MH curve of the latter is not saturated at high fields. These findings indicate a crucial role of the frozen phase separated state in the abrupt transition.
