Title

Structural and Magnetic Properties of Intermediate Oxygen Stoichiometry PrBa₂Cu₂Oₓ

Abstract

The compound PrBa2Cu3Ox (χ ∼ 7) is non superconducting and exhibits antiferromagnetic ordering of the Pr moments at a relatively high temperature of about 17 K. We have investigated the structural and magnetic behavior of PrBa2Cu3Ox for two different oxygen contents (x = 6.9 and 6.4). Magnetic susceptibility measurements show that both these compounds are ordered antiferromagnetically with Néel temperatures of 15.7 and 12.5 K and effective paramagnetic moments of 2.85 μB and 2.94 μB for x = 6.9 and x = 6.4 samples, respectively. The susceptibility (χ) of the x = 6.4 sample shows a pronounced peak typical of antiferromagnetic systems unlike the x = 6.9 sample where χ shows only a slight break and continues to rise even below TN. © 1994.
