Algarabel P. A., Magen C., Morellon L., Ibarra M. R., Albertini F., Magnani N., Paoluzi A., Pareti L., Pasquale M., Besseghini S. Magnetic-field-induced strain in Ni2MnGa melt-spun ribbons. In: Journal of Magnetism and Magnetic Materials, vol. 272-276 pp. 2047 - 2048. Proceedings of the International Conference on Magnetism (ICM 2003), Rome, Italy Edited by D. Fiorani and L. Pareti. Elsevier, 2004.
Linear thermal expansion (300-350 K) and magnetostriction measurements in magnetic fields up to 15 kOe have been performed on a Ni2MnGa melt-spun ribbon. The magnetic-field-induced strain has been studied on a field-cooling process through the martensitic transformation and shows a maximum as a function of the applied field. This previously unreported behaviour is discussed.
