Three-dimensional spin-wave dynamics, localization and interference in a synthetic antiferromagnet
Nature CommunicationsSpin waves are collective perturbations in the orientation of the magnetic moments in magnetically ordered materials. Their rich phenomenology is intrinsically three-dimensional; however, the three-dimensional imaging of spin waves has so far not been ...

Spin-waves in itinerant ferromagnets [PDF]
Journal of Physics: Condensed Matter, 2001 We introduce a novel approach for the investigation of spin-wave excitations in itinerant ferromagnets. Our theory is based on a variational treatment of general multi-band Hubbard models which describe elements and compounds of transition metals. The magnon dispersion is derived approximately as the energy of a variational spin-wave state in the limit
