Nematic phase in strain free detwined BaFe2-xNixAs2

POSTER

Abstract

Here I present the transport and neutron scattering results in BaFe2-xNixAs2. The crystal is detwined using pressure and then the pressure is released at base temperature before the experiment. In the detwined sample, the anisotropy persist at a temperature higher than the both structural and magnetic transition, but the temperature range is much lower than the anisotropy induced by pressure.
