| 摘要 | We measured lifetime and doppler broadening spectra of Sm2/3Sr1/3MnO3+delta as functions of temperature by positron annihilation technology. In terms of lifetime spectrum, we found that the lattice effects triggered by ferromagnetic transition give rise to the change of the coefficient of the average linear thermal expansion of Sm2/3Sr1/3MnO3+delta at T-c. In terms of doppler broadening spectrum, we found the delocalization oj low-momentum electrons occurs in Sm2/3Sr1/3MnO3+delta at metal-insulator transition temperature. |
