We investigated the stability of the charge ordering phases of Ln(1/2)Ca(1/2)MnO(3) (Ln = La, Pr, Nd, Sm, Y, and Ho) and Bi1/4Ca3/4MnO3. Except for Y and Ho, the magnetisation measurements showed a magnetic-field-induced transition which collapse the antiferromagnetic or paramagnetic charge ordering phase to a ferromagnetic phase. H-T phase diagrams were defined. (C) 2000 Elsevier Science B.V. All rights reserved.
