In-plane resistivity measurements as a function of temperature, magnetic field, and its orientation with respect to the crystallographic $ab$ plane were used to study the upper critical field, ${H}_{c2}$, of two overdoped compositions of the iron-based superconductor Ba(Fe${}_{1\ensuremath{-}x}$Ni${}_{x}$)${}_{2}$As${}_{2}$, $x=0.054$ and $x=0.072$. Measurements were performed using precise alignment (with accuracy less …
