Zusammenfassung:Investigations into the magnetic properties of sputtered Mn\(_{x}\)CoGe films in the range \(0.8 \leq x \leq 2.5\) uncovered ferrimagnetic order, unlike the ferromagnetic order reported in bulk samples. These films formed hexagonal Ni\(_{2}\)In-type structures when annealed at temperatures below 600\(^{\circ}\)C. While the Curie temperatures of the films are comparable to those of hexagonal bulk MnCoGe, there is a reduction in the magnetization of the Mn\(_{x}\)CoGe films relative to bulk MnCoGe, and a magnetization compensation point is observed in the \(x
