Comparative study of magnetic quantum oscillations in Hall and transverse magnetoresistance

A. A. Sinchenko, P. D. Grigoriev, A. V. Frolov +5

Magnetic quantum oscillations (MQO) of Hall coefficient are measured in rare-earth tritelluride TmTe $_{3}$ and shown to be much stronger and persist to higher temperature than the…

Charge-Density-Waves Tuned by Crystal Symmetry

A. Gallo-Frantz, A. A. Sinchenko, D. Ghoneim +10

The electronic orders appearing in condensed matter systems are originating from the precise arrangement of atoms constituting the crystal as well as their nature. This teneous rel…

Collective magnetic state induced by charge disorder in the non-Kramers rare-earth pyrochlore Tb $_{2}$ ScNbO $_{7}$

Y. Alexanian, E. Lhotel, R. Ballou +15

Geometrical frustration, as in pyrochlore lattices made of corner-sharing tetrahedra, precludes the onset of conventional magnetic ordering, enabling the stabilization of fluctuati…

Toward equilibrium ground state of charge density waves in rare-earth tritellurides

A. V. Frolov, A. P. Orlov, A. Hadj-Azzem +3

We show that the charge density wave (CDW) ground state below the Peierls transition temperature, $T_{C D W}$ , of rare-earth tritellurides is not at its equilibrium value, but depend…

Bilayer splitting versus Fermi-surface warping as an origin of slow oscillations of in-plane magnetoresistance in rare-earth tritellurides

Pavel D. Grigoriev, Alexander A. Sinchenko, Pascal Lejay +5

Slow oscillations (SlO) of the in-plane magnetoresistance with a frequency less than 4 T are observed in the rare-earth tritellurides and proposed as an effective tool to explore t…
