Query: Rebuttal of "The multicaloric effect in multiferroic materials"   The paper refutes the model and claims published in the Solid State
Communications [1] as well as elsewhere. The theoretical approach proposed in
"The multicaloric effect in multiferroic materials" by Melvin M.~Vopson has a
number of inaccuracies and mistakes. The Author of [1] does not pay necessary
attention to the range of applicability of the derived equations and confuses
the dependent and independent variables. The resulting equations for
electrically and magnetically induced multicaloric effects are incorrect and
cannot be used for measurement interpretation.
