In (Fe80Ga20)1-xBx films, about 10% boron optimizes the tradeoff between magnetostriction (48.8 ppm) and Gilbert damping (6e-3), and the 40 K damping peak amplitude rises with magnetostriction.

Magnetostriction and Temperature Dependent Gilbert Damping in Boron Doped Fe$_{80}$Ga$_{20}$ Thin Films
In (Fe80Ga20)1-xBx films, about 10% boron optimizes the tradeoff between magnetostriction (48.8 ppm) and Gilbert damping (6e-3), and the 40 K damping peak amplitude rises with magnetostriction.
