Low-temperature thermal conductivity of the substrate material YAlO3 and its unconventional sister compound YbAlO3
Parisa Mokhtari, Ulrike Stockert, Stanislav E. Nikitin +3
We present thermal conductivity data on single crystals of YAlO3 and YbAlO3 for temperatures between 2 K and 300 K and the heat current along b and c. Both materials are very good…

Spin dynamics in natural multiferroic pyroxene NaFeSiO
Oleksandr Prokhnenko, Stanislav E. Nikitin, Koji Kaneko +8
Spin dynamics in the natural mineral aegirine, NaFeSiO, a member of the pyroxene family, was studied by elastic and inelastic neutron scattering. Magnetization and specific…

1/5 and 1/3 magnetization plateaux in the spin 1/2 chain system YbAlO3
P. Mokhtari, S. Galeski, U. Stockert +7
Quasi-one-dimensional magnets can host an ordered longitudinal spin-density wave state (LSDW) in magnetic field at low temperature, when longitudinal correlations are strengthened…
