Projektbeschreibung
Vielversprechende schallgetriebene Spinwellen für energieeffiziente Mikrowellengeräte
Spinwellen, die für die Verbreitung von Störungen in magnetischem Material sorgen, könnten eine Möglichkeit sein, um Informationen mit höherer Effizienz und geringerem Energieverbrauch in Mobilgeräten zu übertragen und zu verarbeiten. Jüngste Forschungsarbeiten haben gezeigt, dass sich diese Schwingungen durch Schallwellen steuern lassen. Mit dieser Kopplung könnten energieeffiziente Mikrowellenschnittstellen für Spinwellen bereitgestellt werden, was entscheidend für die Entwicklung von magnetischen Mikrowellengeräten ist. Im Rahmen des EU-finanzierten Projekts MAXBAR sollen Spinwellensignale mit einer geringeren Leistung in hochmoderne Schallwellenresonatoren integriert werden, die vor allem in Hochfrequenz-Kommunikationssystemen eingesetzt werden, um Signale mit unterschiedlichen Frequenzen voneinander zu unterscheiden. Dazu wird das Projektteam Untersuchungen an der Schnittstelle zwischen Nanomagnetismus, Akustik, Mikrowellentechnik und mikroelektromechanischen Systemen durchführen.
Ziel
There is an ever increasing amount of data that needs to be transmitted, processed, and stored by mobile communication technologies like today’s smartphones and tomorrow’s numerous connected devices. Presently, the raw measurement signals need to be amplified, pre-conditioned, and converted to digital signals before they can be processed. Thus, there is clear impetus to supplement next generation radio technologies with analog signal processing functionalities to perform computation directly on the measured signals. By conducting research at the interface between nanomagnetism, acoustics, microwave engineering and micro-electromechanical systems, MAXBAR aims to integrate low power spin-wave signal processing capabilities with state-of-the-art acoustic wave resonators widely used in RF communication systems to distinguish between signals at different frequencies. It is motivated by the premise that the coupling between spin-waves and acoustic waves in nanosystems can be leveraged (i) to overcome the intrinsic limitations plaguing acoustic wave technology, and (ii) to simultaneously deliver an energy efficient microwave interface for spin waves – the holy grail of magnonics. The primary objective is to establish a platform in which strongly hybridized magneto-elastic resonant modes enables new technological functionalities, such as the tunability of bulk acoustic wave filters and the development of non-reciprocity in acoustical wave based delay lines. The project builds upon the host institution’s expertise in microwave measurements of spin-wave propagation, interference processes and magnetization dynamics, while relying on next-generation acoustic wave resonators developed at the secondment institute to demonstrate its objectives. The applicant is an expert in the design, fabrication and characterization of nanomechanical microwave devices and will thus complement its skills by adding nanomagnetism and acoustics in his competences.
