Direct observation of the energy gain underpinning ferromagnetic superexchange in the electronic structure of CrGeTe3 by Watson, MD, Markovic, I, Mazzola, F, Rajan, A, Morales, EA, Burn, DM, Hesjedal, T, van der Laan, G, Mukherjee, S, Kim, TK, Bigi, C, Vobornik, I, Hatnean, MC, Balakrishnan, G, King, PDC

“…From these, together with x-ray absorption spectroscopy and x-ray magnetic circular dichroism measurements, we identify the states created by a covalent bond between the Te 5p and the Cr eg orbitals as the primary driver of the ferromagnetic ordering in this system, while it is the Cr t2g states that carry the majority of the spin moment. …”

Electronic structure and enhanced charge-density wave order of monolayer VSe2 by Feng, J, Biswas, D, Rajan, A, Watson, MD, Mazzola, F, Clark, OJ, Underwood, K, Marckovic, I, McLaren, M, Hunter, A, Burn, DM, Duffy, LB, Barua, S, Balakrishnan, G, Bertran, F, LeFevre, P, Kim, T, van der Laan, G, Hesjedal, T, Wahl, P, King, PDC

“…Moreover, our measurements of both the electronic structure and of X-ray magnetic circular dichroism reveal no signatures of a ferromagnetic ordering, in contrast to the results of a recent experimental study as well as expectations from density functional theory. …”
