14 Oct 2002 | | Subject: | Superconductivity | cond-mat.supr-con | | Abstract: | A novel heterodyne polarimetry system determines the frequency dependence from 900 to 1100 cm^-1 and temperature dependence from 35 to 330 K of the Hall transport in single crystal, optimally doped BSCCO. The results show a significant disconnect from the behavior of the Hall angle in the existing data for YBCO in the far-infrared, which indicate a negative value for the real part of the Hall angle above 250 cm^-1, whereas that of the current work at 1000 cm^-1 is positive. The current work when analyzed using an extended Drude formalism results in a Hall mass comparable to the ARPES Fermi mass and a scattering rate comparable to the low frequency conductivity and Hall effect scattering rates, which, however, are only 1/4 of the ARPES values. | | Source: | arXiv, cond-mat/0210304 | | Services: | Forum | Review | PDF | Favorites | |
