Observation of Phasons in Magnetic Shape Memory Alloy Ni2MnGa
S. M. Shapiro, P. Vorderwisch, K. Habicht +2
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…
Excitations from a Bose-Einstein condensate of magnons in coupled spin ladders
V. O. Garlea, A. Zheludev, T. Masuda +9
The weakly coupled quasi-one-dimensional spin ladder compound (CH)CHNHCuCl is studied by neutron scattering in magnetic fields exceeding the critical field of Bose-…
Momentum-resolved electron-phonon interaction in lead determined by neutron resonance spin-echo spectroscopy
T. Keller, P. Aynajian, K. Habicht +3
Neutron resonance spin-echo spectroscopy was used to monitor the temperature evolution of the linewidths of transverse acoustic phonons in lead across the superconducting transitio…
Spin-Wave Lifetimes Throughout the Brillouin Zone
S. P. Bayrakci, T. Keller, K. Habicht +1
We use a neutron spin-echo method with eV resolution to determine the lifetimes of spin waves in the prototypical antiferromagnet MnF over the entire Brillouin zone. A theor…
