| 中文摘要 | By means of magnetization, resistance, and. electron-spin-resonance measurements at various temperatures it was found that, with increasing temperature, single crystalline Pr0.7Pb0.3MnO3 experiences an unconventional sequence of phase-transition processes, ferromagnetic phase -> ferromagnetic + paramagnetic phase -> superparamagnetic + paramagnetic phase -> paramagnetic phase. Moreover, in the phase-separated temperature range, the metal-insulator transition and the magnetoresistance value are sensitively dependent on the specific processes of temperature change and magnetic field application. On the contrary, the magnetization is process independent. All experimental results can be well understood qualitatively based on a free-energy model considering the distribution of the ferromagnetic phase in the paramagnetic matrix. |
