The internet of things will further enhance the needs for smart microwave electronics. In recent years magnetic materials and collec tive spin excitations (magnons) have experienced increasing interest in th is context\, and the research field magnonics was formed [1]. If coupled t o electromagnetic waves\, magnons promise to shrink wavelengths of relevan t microwave signals by several orders of magnitudes. They allow one to cre ate on-chip microwave devices exploiting the spin of electrons as informat ion carrier –instead of charge– avoiding Joule heating [1\,2]. The min iaturized devices can combine signal transmission and processing including logic operations. In the talk we will discuss recent developments and how nanoengineered magnetic materials as well as self-organized spin structur es such as skyrmions advance both magnonics and the mastering of microwave s [3].     \n[1] A.V.

Current research interests focus on magnetic nanostructures and materials to be exploited in spintro nics\, magnonics and spin caloritronics. He studied physics at the Univers ity of Hamburg\, Germany\, and entered the Philips Research Laboratories\, Hamburg\, Germany\, in 1990 for his Diploma and PhD theses working on sup erconducting sensors for biomagnetism and medical applications. In 1995 Di rk Grundler joined the Microstructure Research Center at the Institute for Applied Physics of University of Hamburg as a postdoctoral researcher inv estigating magnetic properties of low-dimensional electron systems and sem iconductor spintronics. He received the habilitation in experimental physi cs at University of Hamburg in 2001. From 2005 to 2015 he was professor at the Technische Universitaet Muenchen\, Germany\, holding the chair of “ Physics of functional multilayers”.
