Resonant magnetic exciton mode in the heavy-fermion antiferromagnet CeB₆.
An unexpected commonality between the two disparate ground states indicates the dominance of itinerant spin dynamics in the ordered low-temperature phases of CeB(6) and throws new light on the interplay between antiferromagnetism, superconductivity and 'hidden' order parameters in correlated-electron materials.
An exceptionally-high diffraction quality dodecaboride LUB12: Growth and single-crystal structure
The lower symmetry electron-density distribution and the charge transport anisotropy in cubic dodecaboride LuB12.
True symmetry of the electron-density distribution in LuB12 is proved to be much lower than cubic as a result, which correlates very accurately with anisotropy of transport properties of LuB 12.
Maltese cross anisotropy in Ho0.8Lu0.2B12 antiferromagnetic metal with dynamic charge stripes
The model strongly correlated electron system Ho0.8Lu0.2B12 which demonstrates a cooperative Jahn-Teller instability of the boron sub-lattice in combination with rattling modes of Ho(Lu) ions,…
Transport properties of variously doped SmB6
Abstract SmB6 is a heavy fermion semiconductor with a narrow energy gap at the Fermi level, often denoted also as Kondo insulator, which has recently been considered to be a topological Kondo…
Bulk and surface electron transport in topological insulator candidate YbB6–δ
We report the study of transport and magnetic properties of the YbB6–δsingle crystals grown by inductive zone melting. A strong disparity in the low temperature resistivity, Seebeck and Hall…
Surface and bulk components of electrical conductivity in (presumably special topological) Kondo insulator SmB6 at lowest temperatures
Tuning of exchange by band filling in low‐carrier‐density magnet Eu(Gd)B6
We report the study of spin relaxation in the Eu1−xGdxB6 (0 ≤ x ≤ 0.039) single crystals with the help of 60 GHz electron spin resonance (ESR) technique. A drastic change in the linear slopes of the…

Paramagnetic Meissner effect in ZrB12 single crystal with non-monotonic vortex-vortex interactions
The magnetic response related to paramagnetic Meissner effect (PME) is studied in a high quality single crystal ZrB12 with non-monotonic vortex-vortex interactions. We observe the expulsion and…
