Title:
Critical Fluctuations in the Weak Itinerant Ferromagnet ${\mathrm{Ni}}_{3}\mathrm{Al}:$ {{A}} Comparison between Self-Consistent Renormalization and Mode-Mode Coupling Theory 
Abstract:
The magnetic excitations in the weak itinerant ferromagnet Ni3Al have been investigated in the ordered phase as well as in the paramagnetic phase by means of inelastic neutron scattering, in order to search for critical fluctuations. The magnetic excitations have been interpreted within the framework of both itinerant and mode-mode coupling theory (MMT) for an isotropic ferromagnet. The parametrization of the linewidth for the critical scattering shows that the dynamical critical exponent z$\sim...    »
