| 中文摘要 | We investigated the effect of uniaxial and hydrostatic pressure on resistivity and ac-magnetic Susceptibility of two-dimensional layered manganite,La1.2Sr1.75Mn2O7 (LSMO125) to investigate the lattice effect on magnetic and electronic properties. Asymmetric role of uniaxial pressure, parallel to and perpendicular to to c-axis on the spin flop and charge transport has been revealed while comparing hydrostatic pressure. Uniaxial pressure along c-axis increases metal-insulator transition temperature (T-MI) and ferromagnetic ordering temperature (T-C), whereas it decreases the resistivity along ab-plane (rho(ab)) In contrast to pressure along c-axis, T-MI and T-C decrease, whereas the resistivity along c-axis (rho(c)) increases with pressure parallel to to ab-plane. rho(c)/rho(ab) is quite large increasing with pressure and shows a peak at around T-MI. Uniaxial pressure behaviour is strongly related to the Mn-O-Mn linkage between MnO, layers and the spin reorientation from the apical axis to the basal plane and vice versa with pressure. Both rho(ab) and rho(C) decrease whereas T-MI and T-C increases under hydrostatic pressure. Influence of spin and charge on magnetic and electrical properties Underhydrostatic pressure are explained by pressure-induced cant between the MnO2 bilayers and variation in bond lengths The different pressure driving rates of T-MI while measuring rho(ab), and rho(c), confirms that there is a strong competition between the in and Out plane components under hydrostatic pressure.
