We present a comparative investigation under field of three Bi1-xSrxMnO3 manganites in the low-doping regime (xless than or equal to0.50). Powdered samples were investigated in pulsed fields up to 35, 50 or 130T depending on the compound (x=0.25, 0.33, 0.50). Remarkable differences are found in the M(H) curves when comparing the response to the magnetic field of the two different charge-order phases. (C) 2004 Elsevier B.V. All rights reserved.
