## Description

- description: "Materials with magnetic anisotropy can serve as a model object for
    exploring the multicaloric effect because their thermodynamic state alterations
    can be achieved either through the application of a magnetic field H, or by mechanically
    rotating the sample in the magnetic field using torque τ. In such materials, the
    total entropy change \U0001D6E5⁢\U0001D446\U0001D447 arises from two distinct
    contributions: (1) the conventional magnetocaloric effect (MCE) or paraprocess
    \U0001D6E5⁢\U0001D446|\U0001D45A| and (2) the rotational MCE \U0001D6E5⁢\U0001D446\U0001D711.
    In this manuscript, using molecular field model which enables a separation of
    contributions to the total entropy change \U0001D6E5⁢\U0001D446\U0001D447 from
    conventional \U0001D6E5⁢\U0001D446|\U0001D45A| and rotational \U0001D6E5⁢\U0001D446\U0001D711,
    we have determined cross-coupling multicaloric coefficients \U0001D712\U0001D70F,\U0001D43B=(\r\n∂\U0001D70F\r\n∂\U0001D43B\r\n
    \r\n)\U0001D447,\U0001D703 and \U0001D712\U0001D43B,\U0001D70F=−(\r\n∂\U0001D45A\r\n∂\U0001D703\r\n
    \r\n)\U0001D447,\U0001D43B for anisotropic magnetic materials and show that they
    satisfy the basic thermodynamic identities. We also confirmed that the total multicaloric
    effect in the material with magnetic anisotropy can be accurately expressed as
    the sum of the individual magnetocaloric effects induced by separate application
    of the H and τ, minus the magnetic entropy change arising from thermodynamic cross-coupling
    between the subsystems of the solid: \U0001D6E5⁢\U0001D446\U0001D447=\U0001D6E5⁢\U0001D446(\U0001D43B)\r\n\U0001D447,\U0001D70F+\U0001D6E5⁢\U0001D446(\U0001D703)\r\n\U0001D447,\U0001D43B−\U0001D6E5⁢\U0001D446\U0001D450\U0001D45C\U0001D462\U0001D45D\U0001D459\U0001D456\U0001D45B\U0001D454."
