Electro-magnetostatic homogenization of bianisotropic metamaterials

Chris Fietz

We apply the method of asymptotic homogenization to metamaterials with microscopically bianisotropic inclusions to calculate a full set of constitutive parameters in the long wavel…

Frequency dependence of the spin glass freezing temperatures in icosahedral R - Mg - Zn (R = rare earth) quasicrystals

Sergey L. Bud'ko, Paul C. Canfield

We present ac susceptibility measurements with the frequency spanning three orders of magnitude on single grain, icosahedral R - Mg - Zn (R = rare earth) quasicrystals. The freezin…

Spin excitations in KFeSe: linear response approach

Liqin Ke, Mark van Schilfgaarde, Vladimir Antropov

Using \emph{ab initio} linear response techniques we calculate spin wave spectra in KFeSe, and find it to be in excellent agreement with a recent experiment. Th…
