Strange Metal Hall Effect in Underdoped BaFe$_2$(As$_1-x$P$_x$)$_2$

Kavli Affiliate: James Analytis| Summary:The unusual transport properties of strange metals point to the breakdown of the quasiparticle picture, the understanding of which remains one of the most vexing problems in physics. Here, we report investigations of the electrical Hall effect of the strange metal superconductor BaFe$_2$(As$_1-x$P$_x$)$_2$. We show that a doping-independent contribution to…
