Query: Rotating magnetocaloric effect in the ferromagnetic Weyl semi-metal
  Co$_{3}$Sn$_{2}$S$_{2}$   The rotating magnetocaloric effect (RMCE) is a recent interest in magnetic
refrigeration technique in which the cooling effect is attained by rotating the
anisotropic magnetocaloric material from one orientation to the other in a
fixed magnetic field. In this work, we report the anisotropic magnetocaloric
properties of single crystals of the ferromagnetic Weyl semimetal
Co$_{3}$Sn$_{2}$S$_{2}$ for magnetic field $H\parallel c$ axis and $H\parallel
ab$ plane. We observed a significant (factor of $2$) difference between the
magnetocaloric effect measured in both orientations. The rotating
magnetocaloric effect has been extracted by taking the difference of the
magnetic entropy change ($\Delta S_{M}$) for fields applied in the two
crystallographic orientations. In a scaling analysis of $\Delta S_{M}$, the
rescaled $\Delta S_{M}(T,H)$ vs reduced temperature $\theta$ curves collapse
onto a single universal curve, indicating that the transition from paramagnetic
to ferromagnetic phase at 174~K is a second order transition. Furthermore,
using the power law dependence of $\Delta S_{M}$ and relative cooling power
RCP, the critical exponents $\beta$ and $\gamma$ are calculated, which are
consistent with the recent critical behavior study on this compound
\cite{Yan2018}.
