Ferromagnetism makes a doped semiconductor less shiny
F. P. Mena, J. F. DiTusa, D. van der Marel +5
Magnetic semiconductors have attracted interest because of the question of how a magnetic metal can be derived from a paramagnetic insulator. Here our approach is to carrier dope i…

Optical signatures of electron correlations in the cuprates
D. van der Marel
The f-sum rule is introduced and its applications to electronic and vibrational modes are discussed. A related integral over the intra-band part of sigma(omega) which is also valid…

Charge ordering signatures in the optical properties of beta-Na0.33V2O5
C. Presura, M. Popinciuc, P. H. M. van Loosdrecht +4
Temperature dependent optical spectra are reported for beta-Na0.33V2O5. The sodium ordering transition at T_Na = 240 K, and in particular the charge ordering transition at T_MI = 1…
