Spin-wave propagation in alpha-Fe2O3 nanorods: the effect of confinement and disorder

Cortie, David; Casillas-Garcia, Gilberto; Squires, Andrew; Mole, Richard; Wang, Xiaolin; Liu, Yun; Chen, Yen-Hua; Yu, Dehong


Spin-wave excitations in α-Fe2O3 nanorods were directly detected using time-of-flight inelastic neutron spectroscopy. The dispersive magnon features are compared with those in bulk α-Fe2O3 particles at various temperatures to highlight differences in mode intensity and width. The interchanged spectral intensities in the nanorod are a consequence of a suppressed spin orientation, and this is also evident in the neutron diffraction which demonstates that the weak ferromagnetic phase survives to...[Show more]
