Anomalous transport properties are observed in mesoscopic (several hundreds of nanometers to several micrometers) structures of manganite ${\mathrm{Pr}}_{0.65}{({\mathrm{Ca}}_{0.75}{\mathrm{Sr}}_{0.25})}_{0.35}\mathrm{Mn}{\mathrm{O}}_{3}$: (i) spontaneous jumps of resistance occur during both the ramping of magnetic field and the relaxation after the field cycle; and (ii) in certain ranges of temperature and magnetic field, steplike negative differential resistance (NDR) emerges in the current… CONTINUE READING
