SOME EXPERIMENTS ON MAGNETIC INELASTIC SCATTERING OF NEUTRONS

Journal Article · · J. Phys. Soc. Japan
OSTI ID:4635823
>Two methods for studying the thermal excitations that give rise to inelastic scattering are described and shown to give consistent results. The temperature behavior of spin waves in magnetite is investigated. When approaching the Curie temperature, the lifetime and the energy of the spin waves are found to decrease. The temperature region in which the decrease shows up depends on the wavelength of the spin waves. (auth)
