| 中文摘要 | The temperature dependence of magnetization (M) and resistivity (rho) of La(1-x)Sr(x)CoO(3)(x=0.10, 0.33) single crystals have been analyzed. For x=0.10, the temperature dependence of field-cooled magnetization (M(FC)) and zero-field-cooled magnetization (M(ZFC)) is similar to that expected for a canonical spin-glass system. The thermal response of M(ZFC) for x=0.33 indicates a glassy ferromagnetic state. We observe that the ferromagnetic transition temperature T(C) decreases and rho increases rapidly with increasing pressure (P) for the metallic sample (x=0.33), while the dependence of rho on P for the insulating sample (x=0.10) is quite complicated; the pressure coefficient of resistivity (d rho/dT) is sensitive to temperature and applied pressure due to the strong interplay between the pressure-induced band broadening and spin-state transition phenomenon. d rho/dT is large and negative at low-pressure and low-temperature regime while small and positive at high pressures (P>5.4 GPa) and high temperatures (T>110 K). |
