Theoretical Simulation On The Variation In The Transport Behavior Under Pressure And Magnetic Field In La0.825sr0.175mno3

Based on phase separation model and breadth-first traversal algorithm, the spin-related electron transport property of La0.825Sr0.175MnO3 under hydrostatical pressure and magnetic field was systematically simulated. We find that the external hydrostatical pressure has a more important influence on the residual resistivity, high temperature resistivity coefficient, activation energy, and electron scattering of La0.825Sr0.175MnO3 than the external magnetic field. However, the Curie temperature and the magnon scattering are more sensitive to the external magnetic field than to the external hydrostatical pressure in La0.825Sr0.175MnO3.
