Conventional and Acoustic Surface Plasmons on Noble Metal Surfaces: A Time-dependent Density Functional Theory Study
Jun Yan, Karsten W. Jacobsen, Kristian S. Thygesen
First-principles calculations of the conventional and acoustic surface plasmons (CSPs and ASPs) on the (111) surfaces of Cu, Ag, and Au are presented. The effect of interband…
Frustration by competing interactions in the highly-distorted double perovskites La2NaB'O6 (B' = Ru, Os)
A. A. Aczel, D. E. Bugaris, L. Li +4
The usual classical behaviour of S = 3/2, B-site ordered double perovskites generally results in simple, commensurate magnetic ground states. In contrast, heat capacity and neutron…
Magnetic phase transitions in single crystals of the chiral helimagnet Cr1/3NbS2
N. J. Ghimire, M. A. McGuire, D. S. Parker +5
The chiral helimagnet Cr1/3NbS2 has been investigated by magnetic, transport and thermal properties measurements on single crystals and by first principles electronic structure cal…
Complex itinerant ferromagnetism in noncentrosymmetric Cr11Ge19
N. J. Ghimire, M. A. McGuire, D. S. Parker +6
The noncentrosymmetric ferromagnet Cr11Ge19 has been investigated by electrical transport, AC and DC magnetization, heat capacity, x-ray diffraction, resonant ultrasound spectrosco…
