Order from disorder in the double-exchange model
Nic Shannon, Andrey V. Chubukov
The magnetic excitations of the double exchange (DE) model are usually discussed in terms of an equivalent ferromagnetic Heisenberg model. However this equivalence is valid only at…
Enhanced Spin Polarization of Conduction Electrons in Ni, explained by comparison with Cu
K. N. Altmann, D. Y. Petrovykh, G. J. Mankey +5
The spin-split Fermi level crossings of the conduction band in Ni are mapped out by high-resolution photoemission and compared to the equivalent crossing in Cu. The area of the qua…
XPS as a Probe of Gap Opening in Many Electron Systems
Robert Haslinger, Nic Shannon
Core hole photoemission (XPS) provides a powerful indirect probe of the low energy excitations of a many electron system. We argue that XPS can be used to study the way in which a…
XPS and NMR as Complementary Probes of Pseudogaps and Spin-charge Separation
Nic Shannon
The possibility that strongly correlated many-electron systems may exhibit spin-charge separation has generated great excitement, particularly in the light of recent experiments on…
