Abstract :
Structural and magnetic characteristics of Ni-implanted GaP were measured for doses in the range 3–5×1016 cm−2. After subsequent annealing at 700 °C, transmission electron microscopy (TEM) showed residual lattice damage which was more significant in highly carbon-doped epi layers as compared to bulk GaP substrates. The magnetization measurements showed two different contributions, one present at ≤75 K and the other below ∼225 K. No secondary phase formation was detected in either type of GaP.
