Doping-induced redistribution of magnetic spectral weight in substituted hexaborides Ce $_{1 - x}$ La $_{x}$ B $_{6}$ and Ce $_{1 - x}$ Nd $_{x}$ B $_{6}$

S. E. Nikitin, P. Y. Portnichenko, A. V. Dukhnenko +6

We investigate the doping-induced changes in the electronic structure of CeB $_{6}$ on a series of substituted Ce $_{1 - x} R_{x}$ B $_{6}$ samples ( $R$ = La, Nd) using diffuse neutron scatteri…

Large positive correlation between the effective electron mass and the multipolar fluctuation in the heavy-fermion metal Ce $_{1 - x}$ La $_{x}$ B $_{6}$

D. J. Jang, P. Y. Portnichenko, A. S. Cameron +8

For the last few decades, researchers have been intrigued by multipolar ordering phenomena while looking for the related quantum criticality in the heavy-fermion Kondo system Ce$_{…

Pseudo-Goldstone magnons in the frustrated S=3/2 Heisenberg helimagnet ZnCr2Se4 with a pyrochlore magnetic sublattice

Y. V. Tymoshenko, Y. A. Onykiienko, T. Mueller +13

Low-energy spin excitations in any long-range ordered magnetic system in the absence of magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering wave v…
