A new layered cuprate structure-type, (A1−xA′x)14Cu24O41

Ultrafast Dynamics of Photoinduced Electronic Phase Modulation in Ladder Cuprate of Sr14 - xCaxCu24O41

“…The crystal structure is mainly composed of 1D edge-sharing CuO 2 chains and two-leg corner-sharing Cu 2 O 3 ladders as shown in Fig. 1a [5,6]. The chain and ladder planes are stacked alternately along b-axis, as shown in Fig.…”

Raman Scattering Study of (Sr,Ca)10Cu17O29Single Crystals

“…The orthorhombic compound A 10 Cu 17O 29 (where A are alkaline earth and/or trivalent metals) belongs to the spin ladder compounds consisting of two structural modules: A 2 Cu2 O3 and CuO2 with characteristic of them Cu 2 O3 two-leg ladder layers and CuO2 one-dimensional chains [1][2][3][4]. Both modules have identical α and b lattice constants and different incommensurate α parameters.…”

Diffraction streaks from the chimney ladder structure in an (Sr1.5Ca1.5)Cu5+δOy crystal

“…Kato, Takayama-Muromachi, Kosuda & Uchida (1988) have studied M~oCu17029 (M-Bi, Sr, Ca), McCarron, Subramanian, Calabrese & Harlow (1988) have studied (Sr14+xCax)Cu2404~ (x = 0-8) and Siegrist, Schneemeyer, Sunshine, Waszczak & Roth (1988) have studied (A14_xA')Cu24041 (A=alkaline-earth metal, A'--trivalent metal). All of these studies showed that there are two sets of orthorhombic sublattices in the crystals with periods c~"-0.390 and c2-~ 0.275 nm.…”

“…It was recognized that the sublattice with c~ = 0.390 nm is related to a sheet of Cu203 with the Sr and Ca atoms, while the sublattice with c2-~ 0.275 nm is composed of a CuO2 chain. The structures of the crystals have been determined by Kato et al (1988) using a superlattice c=5×0.390= 7x0.275nm and by McCarron et al (1988) and Siegrist et al (1988) using a larger superlattice, c = 7 x 0.390 -~ 10 x 0.275 nm.…”
