Raman study of the phonon symmetries in BiFeO3 single crystals
In bismuth ferrite (BiFeO3), antiferromagnetic and ferroelectric order coexist at room temperature, making it of particular interest for studying magnetoelectric
Read MoreInfrared probe of the insulator-to-metal transition in Ga1−xMnxAs and Ga1−xBexAs
We report infrared studies of the insulator-to-metal transition (IMT) in GaAs doped with either magnetic (Mn) or nonmagnetic acceptors (Be).
