| (a) Schematic coupling of a PM Mn spin between two FM layers. (b) Calculated lateral variation of J_LSC at 30 K. (c) RKKY exchange fields acting on loose Mn atoms derived by fits to the experimental data. Black dots indicate (111) planes in the fcc lattice. The extended plateau on either side of the plot indicates Mn impurities in the direct vicinity of the Co layers experiencing direct magnetic exchange. |
