Abstract
Abstract Discussed in this work are the microstructure, magnetic properties, and exchange bias in (Mn0.7Co0.3)65Sn35 alloy ribbons. After annealing, the crystalline grains grow distinctly from ~0.93 μm to ~8.41 μm. The surface of ribbon samples becomes more regular and dense. The ribbons reveal a ferromagnetism with the Curie temperature TC ~ 169 K, which is determined from the thermomagnetic M(T) measurements. The maximum magnetic entropy change ~4.5 J kg−1 K−1 is obtained around ferromagnetic-paramagnetic transition under the field change of μ0ΔH = 0–7 T. Large exchange bias field of μ0HEB = 80 mT is achieved at T = 2 K when the cooling field is μ0HCF = 0.2 T. The reasons for the appearance of ferromagnetism and large exchange bias effect are discussed.
