Bias sputtering of granular ${\text{L1}}_0$-FePt films with hexagonal boron nitride grain boundaries

Chengchao Xu, B. S. D. Ch. S Varaprasad, David E. Laughlin +2

In this paper, we present an experimental study of ${\text{L1}}_0$-FePt granular films with crystalline/amorphous boron nitride (BN) grain boundary materials for heat assisted magnet…
