“…This shift necessitates the exploration of alternative cooling technologies that are entirely environmentally friendly. − Solid-state cooling based on the giant caloric effect upon the solid-state phase transformation of certain materials has garnered widespread interest, thanks to its zero-global-warming potential and high efficiency. Various caloric effects, including magnetocaloric effect, , electrocaloric effect, , elastocaloric effect, − and barocaloric effect, − corresponding to the magnetic field, electric field, uniaxial stress, and isostatic pressure, respectively, have been extensively explored in recent years. In between them, multicaloric materials that undergo a magnetostructural transformation could respond to more than one field, i.e., magnetic field and stress/pressure, providing a new pathway for solid-state refrigeration. , The coupling between spin and lattice in these materials enables more freedom of application/removing configurations of diverse fields (sequence, size).…”
