Abstract
We have performed a systematic study of magnetic property in La 5/3Sr1/3Ni1 - xCuxO4 system. A spin glass behavior has been observed in a broad Cu substitution range (0.1 ≤ x ≤ 0.65) at low temperature. In lower Cu doping region (0.1 ≤ x ≤ 0.2), the coexistence of stripe or stripe glass phase and spin glass phase was proposed. While in the extremely high Cu doping region, the spin glass feature diminished, and the paramagnetism-like behavior became dominated in the system. Based on the results, a magnetic phase diagram was suggested for La5/3Sr1/3Ni1 - xCuxO4 system from stripe-ordered La5/3Sr1/3NiO4 up to Fermi liquid-like La5/3Sr1/3CuO4 with Cu substitution.
