Electronic structure of Mott-insulator CaCu3Ti4O12: Photoemission and inverse photoemission study

H. J. Im, M. Iwataki, S. Yamazaki +10

We have performed the photoemission and inverse photoemission experiments to elucidate the origin of Mott insulating states in A-site ordered perovskite CaCu $_{3}$ Ti $_{4}$ O $_{12}$ (CCT…

Density-of-states fluctuation-induced negative out-of-plane magnetoresistance in overdoped Bi-2212

Tomohiro Usui, Shintaro Adachi, Takao Watanabe +1

We analyzed the in-plane and out-of-plane magnetoresistance (MR) for overdoped Bi $_{1.6}$ Pb $_{0.4}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ (Bi-2212) single crystals using superconductive fluct…
