Fig. 4From: Enhanced Ferromagnetic Interaction in Modulation-Doped GaMnN Nanorods a–d Raman Stokes spectra of modulation-doped GaMnN nanorods with varied growth time of GaN. The local vibration mode of Mn occupying the Ga site (ωMnN) is observed at 588 cm−1 in modulation-doped GaMnN nanorodsBack to article page
