摘要

Nanostructuring of the Ge_(0.99)Mn_(0.01) single-crystal alloy with the formation of nanowires 60 nm in diameter has been revealed to bring about an increase in the temperature of the percolation transition to the ferromagnetic state to T_(C1) ≈ 45 K and a broadening of the distribution of Curie temperatures in Ge_nMn_m clusters T_(C2) ≈ 125-270 K as compared to Ge_(0.98)Mn_(0.02) thin single-crystal films for which T_(C1) ≈ 6 K and T_(C2) ≈ 270 K.
