Spin Waves in presence of one dimensional magnetic solitons

Previous to the Easter Holidays, in the “Sala de Grados” of the Faculty of Sciences in the University of Zaragoza,  Dr Victor Laliena gave the lecture “Spin waves in presence of one dimensional magnetic solitions”.

“The dinamycs of spin waves is governed by a linearized version of the Landau-Lifshitz-Gilbert equation. The presence of a magnetic soliton induces a kind of potential for the spin waves, whose behaviour in this case shows analogies with the behaviour of quantum particles in presence of a potential (bound states, scattering). In this talk the interaction between  spin waves and a soliton will be analyzed in some detail, discussing the features of bound states (Winter modes) and the peculiarities of scattering, and the analogies/differences with quantum particles.”

Dr Victor Laliena currently works in the University of Zaragoza in the Department of Applied Mathematics and is member of the Multifuntional Magnetic Molecular Materials (M4) team but he has also wide experience in other fields, like Radiophysics and Radiological Protection specialist.
