Role of covalent Fe-As bonding in the magnetic moment formation and exchange mechanisms in iron-pnictide superconductors
K. D. Belashchenko, V. P. Antropov
The electronic origin of the huge magnetostructural effect in layered Fe-As compounds is elucidated using LiFeAs as a prototype. The crucial feature of these materials is the stron…
Strong diamagnetic response of metamaterials
E. N. Economou, Th. Koschny, C. M. Soukoulis
We demonstrate that there is a strong diamagnetic response of metamaterials, consisting of open or closed split ring resonators (SRRs). Detailed numerical work shows that for dense…
An efficient way to reduce losses of left-handed metamaterials
Jiangfeng Zhou, Thomas Koschny, Costas M. Soukoulis
We propose a simple and effective way to reduce the losses in left-handed metamaterials by manipulating the values of the effective parameters R, L, and C. We investigate the role…
Experimental Verification of the Quantized Conductance of Photonic Crystal Waveguides
Weitao Dai, Bingnan Wang, Thomas Koschny +1
We report experiments that demonstrate the quantization of the conductance of photonic crystal waveguides. To obtain a diffusive wave, we have added all the transmitted channels fo…
Geometric Control Over the Motion of Magnetic Domain Walls
N. A. Sinitsyn, V. V. Dobrovitski, S. Urazhdin +1
We propose a method, which enables precise control of magnetic patterns, relying only on the fundamental properties of the wire and the choice of the path in the controlled paramet…
Exotic (anti)ferromagnetism in single crystals of Pr6Ni2Si3
Y. Janssen, K. W. Dennis, R. Prozorov +2
The ternary intermetallic compound Pr6Ni2Si3, is a member of a structure series of compounds based on a triangular structure where the number of Pr atoms in the prism cross section…
