Goldman X-ray magnetic circular dichroism (XMCD) measurements on single-crystal and powder samples of Ba 0.6 K 0.4 Mn 2 As 2 show that the ferromagnetism below T C ≈ 100 K arises in the As 4 p conduction band. No XMCD signal is observed at the Mn x-ray absorption edges. Below T C , however, a clear XMCD signal is found... [Phys. Rev. Lett. 114, 217001] Published Wed May 27, 2015
