Abstract Large rotating magnetocaloric effect (MCE) has been observed in some single crystals due to strong magnetocrystalline anisotropy. By utilizing the MCE, a new type of rotary magnetic refrigerator can be constructed, which could more simplified and efficient than conventional one. However, compared with polycrystalline materials, high cost complexity preparation for hinder development this novel refrigeration technology. For first time, here we observe giant MCE textured DyNiSi material, is larger those most refrigerants reported so far. This result suggests that compound attractive candidate refrigerator. considering influence demagnetization on origin large attributed coexistence anisotropy highly preferred orientation. Our study not only provides refrigerant low temperature refrigeration, but also opens way exploit materials will beneficial
