Orbital selective of kondo lattice
WebKondo hybridization developsbelow ~80K. Our calculationsindicate the antiferromagnetism and Kondo lattice to reside predominantly on different f-orbitals, promoting orbital selectivity as a new conception into how these phenomena coexist in heavy-fermions. Finally, at 45 K, we find a novel first order–like transition through abrupt WebOur results present the distinct observation of the orbital selective 5f electron character, indication of Kondo effect, and together with the subatomic features of individual 5f impurity magnetic ...
