  5. Magnetic Shape Memory Effect Ferromagnetic shape memory alloys (FSMA) are smart materials possessing not only ferromagnetic as well as thermal shape memory properties but also large magnetic field induced strains. In single crystalline Ni2MnGa bulk material, strains as large as 10% have been realized.  Principle of magnetic field induced re-orientation of martensitic variants.

  10. Tm TN=54K ? From Zochowski et al.[cap dilatometry J. Magn. Magn. Mat. 104-107, 1515 (1992). ]. .... Strongly anisotropic Systems have to be measured with great care !!! M.Rotter „Magnetostriction“ Course Lorena 2007

  11. Tm Forced magnetostriction of Tm a single crystal. Circles represent the data measured by Zochowski et al.[cap dilatometry J. Magn. Magn. Mat. 104-107, 1515 (1992). ]. Squares represent the data obtained by Barcza. [TU Vienna]. Crosses represent the neutron diffraction data obtained at IN12. Triangles the data obtained by A. Lindbaum glueing the sample [TU Vienna].
