line graph shows HD and ribbon samples sintered, heat treated, and diffusion treated using the same procedure. HD sample used the PrCuAl powder that was hydrogen decrepitated before ball milling, while the ribbon sample used the normal PrCuAl powders. The HD treated PrCuAl powder helps the grains to be better aligned.

New family of materials hosting magnetic Fermi arcs

Fermi arcs were so far found only in superconducting cuprates and certain class of semimetals, where they span pairs of Weyl fermions of opposite chirality. We recently discovered Fermi arcs that emerge in a simple cubic compound, NdBi, when the sample orders antiferromagnetically.
