Magnetic Anisotropy, Spin Pinning and Exchange Constants of (Ga,Mn)As films

Ying-Yuan Zhou, Yong-Jin Cho, Zhiguo Ge +3

We present a detailed investigation of exchange-dominated nonpropagating spin-wave modes in a series of 100 nm Ga${}_{1-x}$Mn${}_x$As films with Mn concentrations $x$ ranging from…
