Weak Localization in Ferromagnetic (Ga,Mn)As Nanostructures.
Physical Review Letters 99 (11), p. 116803.
We report on the observation of weak localization in arrays of (Ga,Mn)As nanowires at millikelvin temperatures. The corresponding phase coherence length Lϕ is typically between 100 and 200 nm at 20 mK. Strong spin-orbit interaction in the material is manifested by a weak antilocalization correction around zero magnetic field.
