| 中文摘要 | The doping effect of Sr and transition metals Mn, Fe, Co into the direct-gap semiconductor LaZnAsO has been investigated. Our results indicate that the single phase ZrCuSiAs-type tetragonal crystal structure is preserved in (La-1-Sr-x(x))(Zn1-xTMx)AsO (TM = Mn, Fe, Co) with the doping level up to x = 0.1. While the system remains semiconducting, doping with Sr and Mn results in ferromagnetic order with T-C similar to 30 K, and doping with Sr and Fe results in a spin-glass-like state below similar to 6K with a saturation moment of similar to 0.02 mu B/Fe, an order of magnitude smaller than the similar to 0.4 mu B/ Mn of Sr-and Mn-doped samples. The same type of magnetic state is observed neither for (Zn, Fe) substitution without carrier doping, nor for Sr- and Co-doped specimens. Copyright (C) EPLA, 2013 |
