“…The magnetic hardness of MnAl-based alloys stems from the magneto-crystalline anisotropy of Mn-Mn sulfide, which mainly originates from the crystal field effect. [17][18] The cubic CsCl-type phase, as the FeAl-based alloys, is magnetically soft with small magnetic moment, [27][28] but unfortunately such a binary MnAl phase has not been observed. [17][18][19][20] Therefore, an effective way to acquire good magnetocaloric performance in MnAl-based alloys would be to reasonably tune the Mn-Mn atomic distances and reduce the crystalline asymmetry.…”

Magnetic refrigeration technology based on the magnetocaloric effect (MCE) of magnetic substances has been considered a prominent, energy‐efficient, and environmentally benign cooling method. Exploring suitable magnetic substances is a prerequisite for practical applications. A family of rare‐earth‐free magnetocaloric materials called Mn30Fe20−xCuxAl50 alloys is identified room‐temperature refrigeration, which are derived from the well‐known MnAl‐based permanent magnets. As expected from experimental and theoretical investigations, all of the Mn30Fe20−xCuxAl50 alloys are crystallized in a stable cubic CsCl‐type crystal structure, revealing a single second‐order type magnetic phase transition (MPT) with tunable MPT temperature. They also exhibit a large reversible MCE and good magnetocaloric performances in a wide temperature range. Crucially, these Mn30Fe20−xCuxAl50 alloys represent a rare case of magnetic materials belonging to a large family that can be fabricated from low‐price, earth‐abundant, and non‐toxic elements. They could provide new choices for practical room‐temperature magnetic refrigeration applications.
