The crossed‐field and single‐field Hall effect in LuRh2Si2
Abstract
The Hall effect of LuRh2Si2 - the non-magnetic homologue of the heavy-fermion material YbRh2Si2 - is studied with two different setups: in the conventional single-field geometry, the field dependence is analyzed in terms of the differential Hall coefficient. Beyond that, the recently developed crossed-field experiment allows to examine the linear-response Hall coefficient as a function of magnetic field. The results reveal the expected analogy between both experiments which corroborates the equivalent findings in YbRh2Si2. This emphasizes the feasibility to investigate field-induced quantum critical points with both methods. Setup of the crossed-field Hall-effect experiment allows to examine the linear-response (with respect to the magnetic field B1) Hall coefficient as a function of tuning field B2. © 2010 WILEY-VCH Verlag GmbH & Co.
