Coulomb blockade and magnetoresistance in granular La1.32Sr1.68Mn2O7 under hydrostatic pressure

Abstract

AbstractThe transport properties in the La1.32Sr1.68Mn2O7 layered manganite system have been studied in the presence of magnetic field up to 5T. An analysis of the low temperature (T<45K) dependence of the resistivity under hydrostatic pressure up to 25kbars shows the spin-dependent Coulomb Blockade phenomenon. The surface phase and the link condition in grain boundaries are suggested to be responsible for the magnetoresistance data while influencing the charge transfer probability between grains
