Antiferromagnetic-insulating (AF-I) and ferromagnetic-metallic (FM-M) phases coexist in various half-doped manganites over a range of temperature and magnetic field, and this is often believed to be an essential ingredient of their colossal magnetoresistance. We present magnetization and resistivity measurements on Pr 0.5 Ca 0.5 Mn 0.975 Al 0.025 O 3 and Pr 0.5 Sr 0.5 MnO 3 showing that the fraction of the two coexisting phases at low temperature in any specified measuring field, H, can be… Expand
