Ferromagnetic properties of MnSix and MnGex thin layers prepared by pulsed laser ablation.
Original language description
Pulsed laser deposition and post-annealing was used for the preparation of MnSix and MnGex thin layers in order to study the increase of ferromagnetic properties related to crystalline phases. As-prepared samples were mainly amorphous with Mn concentration ranging from 20 to 50 at.%. Annealing of MnSix and MnGex layers at 600 °C and 350 °C, respectively, led to the formation of crystalline nanoparticles with the diameter from 10 to 20 nm. Magnetization measured at 300 K showed that the annealed MnSix layers exhibited magnetization of 0.07 μB/Mn atom. Magnetization of annealed MnGex layers varied depending on Mn concentration from 0.1 μ B/Mn atom (30 at.%) to 0.4 μ B/Mn atom (47 at.%). Resistivity measurements of the annealed layers showed values typical for highly degenerate silicon (~10-3.Ω.m) and germanium (~10-5.Ω.m). Temperature dependence of resistivity revealed that, after annealing, only MnSix layers with lower Mn concentration preserved a semiconducting behaviour.
