摘要：

The motion of twin boundaries in Ni-Mn-Ga ferromagnetic shape memory alloy (FSMA) particles embedded in a polymer matrix has been proposed as an effective mechanism for the dissipation of vibration energy. Indirect evidence of the motion of these boundaries through vibrating sample magnetometer measurements on FSMA/polyurethane matrix composite is shown. (C) 2003 Published by Elsevier B.V.
