The rotating magnetocaloric effect (RMCE) in polycrystals, harnessing the demagnetizing effect, offers a promising alternative for magnetic refrigeration. Traditional RMCE studies have focused on materials with magnetocrystalline anisotropy, which are costly and fragile. This work demonstrates that the RMCE can be achieved in any polycrystalline magnetocaloric sample with an asymmetric shape, without requiring magnetocrystalline anisotropy. Using gadolinium as a case study, the authors provide a theoretical framework for computing the demagnetizing field-based RMCE and present experimental verification for different magnetic field intensities and temperature ranges. Direct measurements reveal a significant adiabatic temperature difference (1.2 K) and refrigerant capacity (7.44 J kg\(^{-1}\)) within low magnetic field amplitudes (0.4 T). Utilizing lower magnetic field intensities in a magnetocaloric heat pump can significantly reduce the need for permanent magnet materials, reducing the overall device cost, size, and weight, enhancing the feasibility of mass-producing such devices. The study also highlights the potential of using low magnetic fields, which could reduce the amount of permanent magnet material used, and the importance of further exploration in different materials and device architectures to exploit this effect.The rotating magnetocaloric effect (RMCE) in polycrystals, harnessing the demagnetizing effect, offers a promising alternative for magnetic refrigeration.
