High temperature linear magnetoresistance and scaling behavior in the Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ series

Rohit Kumar, Surjeet Singh, Sunil Nair

We present magnetotransport studies of the parent, an underdoped and an optimally doped composition of the Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ series. We observe that both…
