Abstract

Transport properties of (formula presented) (formula presented) have been investigated in the temperature range 15–300 K in external magnetic fields up to 1.5 T and hydrostatic pressure up to 1 GPa. The 4% Ru doping in Mn site converts the low-temperature robust orbital ordered phase observed in the undoped compound to a two-phase (ferromagnetic and charge ordered) ground state. As a result of such doping (phase-separated ground state), colossal magnetoresistance, slow relaxation of resistivity with logarithmic time dependence, and prehistory effects that are enhanced by pressure are observed in (formula presented) In contrast, the above effects are absent in (formula presented).
