Theoretical investigation of rotating magnetocaloric effect in PrRu2

•Rotating magnetocaloric effect in ferromagnetic PrRu2 compound.•Crystalline electrical field anisotropy in cubic Pr3+ compound.•Magnetocaloric effect around spin reorientation phase transition.•Influence of spin reorientation on the magnetocaloric effect. The magnetic anisotropy in the cubic ferromagnetic PrRu2 compound (TC = 34 K) is due to the crystalline electrical field interaction. Using a model Hamiltonian which includes the crystalline electrical field, exchange and Zeeman interactions we calculated the rotating magnetocaloric effect, considering the magnetic field changes along the three main cubic crystallographic directions 〈001〉, 〈011〉 and 〈111〉. The influence of the spin reorientation, along the field directions, on the magnetocaloric potentials were quantitatively obtained and discussed.
