The AC conductivity of samarium phosphate glasses
The AC conductivity of SIGMA(AC) samarium phosphate glasses with different Sm2O3 content is measured in frequency range of 10^3 to 10^7 hz over the temperature range of300 to 553 K. The observed frequency dependence can be expressed as SIGMA(AC)=AW^s, where 0.6 < s < 1 which confirms the elect...

| Summary: | The AC conductivity of SIGMA(AC) samarium phosphate glasses with different Sm2O3 content is measured in frequency range of 10^3 to 10^7 hz over the temperature range of300 to 553 K. The observed frequency dependence can be expressed as SIGMA(AC)=AW^s, where 0.6 < s < 1 which confirms the electron hopping phenomena. The bulk conductivity increases with the increasing temperature and decreases with the increasing neodymium content. |
