Highly mobile carriers in orthorhombic phases of iron-based superconductors FeSe${}_{1-x}$S${}_x$

Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +4

The field and temperature dependencies of the longitudinal and Hall resistivity have been measured for FeSe${}_{1-x}$S${}_x$ (x=0.04, 0.09 and 0.19) single crystals. The sample F…
