We show that minimal disturbance to the robust charge orderedPr(0.5)Ca(0.5)MnO(3) by 2.5% Al substitution on Mn-site drives the systemtowards ferromagnetic ground state. The history-dependent coexisting phasesobserved are explained as an outcome of a hindered first order transition withglass like arrest of kinetics resulting in irreversibility. Consistent with asimple phase diagram having ferromagnetic ground state, it is experimentallyshown that these coexisting phases are far from the equilibrium.Comment: This version is Accepted in Physical Review
