Description

Mutual stabilizing influence of Y and Ni on An+1BnO3n+1 structure stability during synthesis of Ni-containing cuprates with general formula (Ln, Sr, Y)3Cu1.5Ni0.5O6 (Ln=La, Nd, Pr) is detected. New complex oxides of copper and nickel are obtained, their structural and thermal characteristics are investigated. Temperature dependences of electric conductivity of compounds obtained have semiconducting character and are interpreted in the framework of jump model with variable length of free running

Abstract (Russian)

Обнаружено взаимное влияние Y и Ni на устойчивость структуры An+1BnO3n+1 при синтезе Ni-содержащих купратов общей формулы (Ln, Sr, Y)3Cu1.5Ni0.5O6 (Ln=La, Nd, Pr). Получены новые сложные оксиды меди и никеля, исследованы их структурные и термические характеристики. Температурные зависимости электропроводности полученных соединений имеют полупроводниковый характер и интерпретируются в рамках прыжковой модели с переменной длиной свободного пробега
