Objetivo The project aims at studying spin-wave excitations from nanocontacts and implementing biological inspired computations with wavefronts in nano-structures, likely in terms of spin waves in ferromagnetic films. This implies building a bridge between Mathematical Neuroscience and Applied Physics. It is also of great importance to create a new research line at the \emph{Magnetics Laboratory Group} at UB with Prof. J. Tejada and Dr. J. M. Hernandez based on nanofabrication of magnetic devices sensors in order to study gyromagnetic phenomena and the patterning of spin dynamics at the quantum level.Nanoscale, current controlled spin-torque oscillators (STOs) are of great fundamental interest and also of interest for signal processing and communication, including on-chip communication via spin-wave propagation. However, the fundamental characteristics of the spin-waves emitted by STOs are unknown. STOs, consisting of a point contact to a thin film ferromagnet (FM), were first proposed theoretically in 1996. High DC current densities generate a high-frequency dynamic response (up to 100 GHz) in the FM layer and can result in the emission of spin-waves. Studies of STOs to date have relied primarily on electronic transport characteristics. Further studies have shown these oscillations may be phase-locked to an external rf source, via a process known as injection locking, providing a means of conducting time-resolved spatial imaging. The aim of the proposed work is to study the fundamental characteristics of spin-waves generated from STOs using full-field transmission x-ray microscopy (TXM), combined with x-ray magnetic circular dichronism (XMCD) to provide magnetic contrast.We will determine the physical requirements for implementation with STO’s of a novel computational framework based on polychronous wavefront dynamics using temporal and spatial patterns of activity in pulse-propagating media.
