Giant Rotating Magnetocaloric Effect in the Region of Spin-Reorientation Transition in the NdCo5 Single Crystal

We have investigated the anisotropy of the magnetocaloric effect in a NdCo5 single crystal in a wide range of temperatures, including the spin-reorientation temperature region. In the field mu H-0 = 1.3 T in the spin-reorientation region 250-310 K, we discovered a giant rotating magnetocaloric effect of similar to 1.6 K, caused by rotation of the magnetization vector. The calculations of the anisotropy magnetocaloric effect for the field mu H-0 = 1.3 T have been carried out.
