Magnetic anisotropy in YbRh6Si4 single crystals — •Sebastian Witt, Doan-My Tran, and Cornelius Krellner — Physikalisches Institut, Goethe University Frankfurt, D-60438 Frankfurt
Recently, researchers have started to investigate the structural properties of rhodium-rich silicides RERh6Si4 (RE = rare earth) [1]. The new interest in these hexagonal and non-centrosymmetric compounds derives from the suppression of a ferromagnetic transition to a quantum critical point in Si-doped CeRh6Ge4. Recently, a magnetic transition at 4.5K in YbRh6Si4 polycrystals was reported.
Here, we present the single crystal growth of YbRh6Si4 with indium flux. In first measurements (susceptibility, resistivity and specific heat) we have investigated the magnetic transition around 4.5K in needle-shaped single crystals. In susceptibility and resistivity data the magnetic anisotropy for field along and perpendicular to the c-direction will be presented.
