Abstract: Contrary to the sister superconducting (Ba,K)Fe$_2$As$_2$ materials with partial hole substitution, the electron-doped Ba(Fe,Tm)$_2$As$_2$ pnictides (where TM is a transition metal) remain relatively understudied so far. In the review, we summarize current advances in the studies of microstructural, transport, magnetic, calorimetric, optical, band-structure properties of Ba(Fe,Tm)$_2$As$_2$ family pnictides, as well as the structure of the superconducting order parameter and its evolution with the change in the electron doping degree.
