Abstract
Materials showing anisotropic magnetocaloric effects could open the way for new designs of magnetic cooling. In the paper by Jin et al. [Phys. Rev. B 83, 184431 (2011)], a rotating magnetocaloric effect was pointed out in single crystals. The reported effect arises from the rotation of crystals between their and axes. However, in this Comment we demonstrate that crystals generate a rotating magnetocaloric effect that is at least two times larger than that reported by Jin et al. On the other hand, the newly reported rotating magnetocaloric effect is not directly resulted from the magnetocrystalline anisotropy, also being in contrast with Jin et al. data.
