The ferromagnetic metallic oxide, SrRuO3 (T-C similar to 165 K) undergoes structural, magnetic and metal-insulator transitions upon substitution of Cu at the Ru-site. For x = 0.2 in SrRu1-xCuxO3, the structure becomes a tetragonal with the space group I4/mcm and there is a signature of both ferromagnetic (T-C = 65 K) and anti ferromagnetic (T-N = 32 K) ordering due to possible magnetic phase separation. The anti ferromagnetism arises due to short range ordering of Cu- and Ru-moments. Jahn-Teller distortion of (Ru,Cu)-O-6 octahedra indicates that the copper ions are in 2+ oxidation state with t(2g)(6)e(g)(3) electronic configuration. For x >= 0.1, narrowing of Ru-4d bandwidth by the substitution of Cu ions results in semiconducting behavior. For x = 0.3, the ac and dc susceptibility measurements indicate a spin glass behavior. The origin of spin glass behavior has been attributed to competing ferromagnetic and anti ferromagnetic interactions. (C) 2008 Elsevier Ltd. All rights reserved.
