    Magnetic anisotropies in Ni-Mn-Ga films on MgO(001) substrates

    No full text
    Ferromagnetic resonance was used to study the influence of temperature and film thickness on magnetic properties of Ni-Mn-Ga films deposited on single crystal MgO(001) substrates. It has been shown that depending on the film thickness and preparation condition, three configurations of magnetic anisotropy can be realized in these films. The temperature dependence of the anisotropy field is determined

    Temperature dependence of magnetically induced strain in single crystal samples of Ni–Mn–Ga

    We investigate the effect of temperature and applied magnetic field on the strain behavior of oriented single crystal samples of Ni2MnGa. It is shown that the martensite twins can be partially oriented by the application of a magnetic field during cooling from the austenite state, observing a strain of the order of 1%. Depending on the final cooling temperature, a different value of magnetically induced strain is observed in the martensite phase, an effect due to the irreversible alignment of a fraction of the martensite twins to the magnetic field direction. The results are discussed with reference to different experimental procedures and the shape memory characteristics of the allo

    EFFECT OF TEXTURING ON THE MAGNETICALLY ACTIVATED PROPERTIES OF POLYCRYSTALLINE NIMNGA ALLOYS

    We present structural and magnetostrain data obtained on as cast and annealed bulk polycrystalline Ni2MnGa samples with a defined grain orientation. A peak cyclic strain of the order of 10-4 is found, due to the readjustment of martensite structures under applied field. Annealing may produce positive effects on the austenite to martensite transition and on strain. These experimental results are discussed with reference to previously published data on single crystals and randomly oriented polycrystalline samples
