Abstract

The effect of oxygen content δ on metal-insulator transition in Sm_1.85CeO_0.15CuO_4+δ antiferromagnetic superconductors are reported. The oxygen content parameter δ was obtained by the iodometric titration method using the parent compound Sm₂CuO₄ as the standard based on Ce⁴⁺ valence. The magnetic susceptibility data were obtained through a SQUID magnetometer from 2-300 K.
