Abstract
- Abstract: We report structural, DC magnetization, linear and non-linear AC susceptibility for phase pure RuSr2Y1.5Ce0.5Cu2O10 (YRu-1222) magneto-superconductor. The studied compound is synthesized through HPHT (high pressure high temperature: 6GPa, 1400°C) technique at NIMS-Japan. As synthesized YRu-1222, is crystallized in single phase tetragonal structure with space group I4/mmm. DC magnetic susceptibility showed that studied YRu-1222 is a magneto-superconductor with Ru spins magnetic ordering at around 120K and superconductivity in the Cu-O2 planes below ∼40K. The frequency and field dependent AC susceptibility measurements confirmed the spin-glass (SG) behavior with homogenous/non-homogenous ferromagnetic clusters for the studied system. The frequency variation followed the Vogel–Fulcher law with homogeneous/non-homogenous magnetically interacting ferromagnetic clusters embedded in spin-glass (SG) matrix. Detailed linear and non-linear AC susceptibility measurements are carried out to probe the exact magnetic nature of the studied magneto-superconductor YRu-1222. [Copyright &y& Elsevier]
