Anisotropic Resistivities of Precisely Oxygen Controlled Single-CrystalBi2Sr2CaCu2<

Abstract: The in-plane resistivity r a ͑T ͒ and the out-of-plane resistivity r c ͑T ͒ have been systematically measured for Bi 2 Sr 2 CaCu 2 O 81d single crystals with their oxygen contents precisely controlled. In the underdoped region, deviation from T-linear in-plane resistivity, which evidences the opening of the "spin gap," is clearly observed, while the out-of-plane resistivity is well reproduced by the activationtype phenomenological formula r c ͑T ͒ ͑a͞T ͒ exp͑D͞T͒ 1 c. In contrast to the YBa 2 Cu 3 O 72d system… Show more

“…Although this seems unusual, NbSe 2 , one of the most widely studied CDW systems [18][19][20] , displays a similar phenomenon. Furthermore, analogous effects have been seen in the high-temperature superconducting cuprates around the pseudogap temperature 21 , which some ascribe to a CDW transition 22 .…”

“…deviation from high-temperature linear behavior below a certain temperature T * ρ ab , as reported in our previous papers. 25,30) T * ρ ab is estimated to be 209 and 153 K for p = 0.11 and p = 0.16, respectively. Here, T * ρ ab is estimated as the temperature at which ρ ab decreases 1% from the high temperature linear behavior.…”
