"Observation of phasons in the magnetic shape memory alloy Ni2MnGa";
EPL (Europhysics Letters), 77 (2007), 5; 56004-1 - 56004-5.



English abstract:
An inelastic neutron scattering study of the lattice dynamics of the martensite phase of the ferromagnetic shape memory alloy, Ni2MnGa, reveals the presence of well-defined phasons associated with the charge density wave (CDW) resulting from Fermi surface (FS) nesting. The velocity and the temperature dependence of the phason are measured as well as the anomalous [110]-TA2 phonon.
