Ferromagnetic insulators offer low magnetic damping, and potentially efficient magnetic switching, making them ideal candidates for spin-based information processing. Here, Zheng et al introduce a ferromagnetic insulator spinel, Li0.5Al1.0Fe1.5O4, with low magnetic damping, perpendicular magnetic anisotropy, and no magnetic dead layer.
