Abstract

A solid solution of the quasi-one-dimensional cuprate, (Ca1-xYx)0.82CuO2 with 0 ≤ x ≤ 0.435, has been successfully synthesized at room pressure. Upon yttrium doping (decreasing hole concentration), the formal Cu valence of the solid solution changes from + 2.36 to + 2.00 without any significant change in the crystal structure. The solid solution shows an evolution in magnetic behavior, from a dimerlike spin state to a long-range, magnetically ordered state. The former state can be treated as a dilute one-dimensional spin system consisting of both spin dimers (S = 0) and paramagnetic spin segments (S = 1/2).
