Abstract: Recently, specific heat and magnetization measurements on single
crystalline CeRu4Sn6 revealed pronounced anisotropies [1], suggesting
that this compound may be a nodal Kondo insulator. Amazingly, strong
anisotropy was not only found along the fundamental crystal directions
(tetragonal a- and c-direction) but also within a quasi cubic cell arising in
this compound due to the lattice parameter in the [0 0 1] direction (c)
almost matching the lattice spacing in the [1 1 0] direction (c'). Here, we
present and discuss results of electrical resistivity measurements on
single crystalline CeRu4Sn6 samples down to 25 mK for different
magnetic fields up to 15 T aligned parallel to the tetragonal a- and cdirection
and to the quasi-cubic c'-direction.
