Anisotropic magnetoelastic coupling in the honeycomb magnet Na $_{3}$ Co $_{2}$ SbO $_{6}$

Prashanta K. Mukharjee, Sebastian Erdmann, Lichen Wang +8

We present magnetization and dilatometry measurements on the honeycomb cobaltate Na $_{3}$ Co $_{2}$ SbO $_{6}$ and map out its detailed field-temperature phase diagram down to sub-Kelvin tem…

Elastoresistance as probe of strain-controlled entropy from Kondo scattering

Soumendra Nath Panja, Jacques G. Pontanel, Julian Kaiser +2

Heavy-fermion metals are prototype correlated electron systems for the study of Kondo entanglement and quantum criticality. We use the symmetry decomposed elastoresistance to uncov…

Intermediate field-induced phase of the honeycomb magnet BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$

Prashanta K. Mukharjee, Bin Shen, Sebastian Erdmann +6

We use magnetometry, calorimetry, and high-resolution capacitive dilatometry, as well as single-crystal neutron diffraction to explore temperature-field phase diagram of the anisot…

Metallic conductivity on Na-deficient structural domain walls in the spin-orbit Mott insulator Na $_{2}$ IrO $_{3}$

Franziska A. Breitner, Julian Kaiser, Anton Jesche +1

Honeycomb Na $_{2}$ IrO $_{3}$ is a prototype spin-orbit Mott insulator and Kitaev magnet. We report a combined structural and electrical resistivity study of Na $_{2}$ IrO $_{3}$ single crystal…
