| 中文摘要 | The magnetic properties of Nd(0.85)Sr(0.15)CoO(3) have been systematically investigated by dc magnetization, ac susceptibility and magnetic relaxation. The dynamics scaling analysis of ac susceptibility and magnetic relaxation give sufficient evidence of the existence of a spin-glass phase, which can be ascribed to the complicated interactions among Co(3+) and Co(4+) ions in this phase-separated compound. The field-cooled magnetic hysteresis loop displays both horizontal and vertical shifts, i.e., the exchange bias effect, while no shifts are present with increase of the measuring field up to +/- 50 kOe. The results further sustain the picture of the spin-glass phase coexisting with other magnetic regions in the sample. (C) 2011 Elsevier B.V. All rights reserved. |
