Abstract
In this paper, a phenomenological model is used to calculate magneto-caloric properties of Ge0.95Mn0.05 films fabricated with substrate temperatures of 85, 100, and 120 ∘C. Calculations showed that the ferromagnetic Mn5Ge3 phase improves magneto-caloric properties of the Ge0.95Mn0.05 films. It is suggested that Ge0.95Mn0.05 films are suitable candidates as refrigerants near room-temperature region.
