摘要：

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 TbMnO3 single crystals. The reported effect arises from the rotation of TbMnO3 crystals between their b and a axes. However, in this Comment we demonstrate that TbMnO3 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.
