Abstract :
We studied structural and magnetic properties of Fe doped Ni2.15Mn0.79Fe0.06Ga ferromagnetic shape memory ribbons prepared by a melt-spinning method. Experimental results obtained indicate that martensitic phase transition temperatures of the ribbon strongly depend on annealing, hence on the degree of atomic ordering. Magnetic hysteresis loop of the as-prepared ribbons shows a feature that can be attributed to the coexisting ferro and antiferromagnetic interactions.
