Designing with spins: thermal nanopatterning of spin textures for magnonics
Speaker: Prof. Edoardo Albisetti, Politecnico di Milano
- Thermally assisted magnetic scanning probe lithography (tam-SPL) is used for patterning reconfigurable magnetic structures with unprecedented properties.
- Complex 2-, 1-, 0-dimensional spin textures (such as domain walls and vortices) with tailored topology and geometry are patterned in ferromagnetic films with exchange bias.
- Nanopatterned spin textures are used for controlling at the nanoscale the emission, propagation and confinement of spin waves.
- Optically inspired spin-wave platforms based on magnonic nanoantennas and waveguides are demonstrated.
Finding new ways for controlling the magnetic properties of thin films with nanoscale resolution is of paramount importance for developing next-generation devices for storage and processing. I will discuss recent results on the use of thermally assisted magnetic scanning probe lithography (tam-SPL) for creating reconfigurable magnetic nanostructures, and realizing integrated circuits for generating and manipulating spin-waves, towards the realization of nanoscale platforms for beyond-CMOS magnetic computing.
Edoardo Albisetti is an Assistant Professor at the Department of Physics, Politecnico di Milano. He received his Ph.D. in Physics from Politecnico di Milano in 2014 with a thesis on Magnetic Tunnel Junctions for Biosensing, visiting Georgia Tech, U.S. and CIC Nanogune, Spain. In the framework of his Marie Skłodowska-Curie global fellowship, he was a PostDoc in CUNY Advanced Science Research Center and New York University, USA. His research interests include nanomagnetism, spin-dynamics and nanoelectronics, with a focus on finding unconventional ways for tailoring the physical properties of matter at the nanoscale.
Webinar Series description
The “NanoFrazor Technology” webinars will explain the main features and limitations of NanoFrazor lithography. They will be hosted by the key experts of our R&D teams. You will learn how our technology works, and where and why it is superior or inferior to conventional nanolithography techniques. We will also share the results and insights of our ongoing development projects.
The “NanoFrazor Applications” series will show examples from different application fields, where the NanoFrazor was used to fabricate unique nanopatterns and devices. The guest speakers - scientists who actively use NanoFrazor - will talk about their work and recent results.
The “NanoFrazor Sales” webinars will focus on NanoFrazor products. We will talk about hardware components and software features of the NanoFrazor systems. We will also cover the cost-of-ownership and how to receive a quick return on investment. Finally, we will also offer a dedicated webinar where you will learn about the various funding options for NanoFrazor systems and how to maximize your chances to get your funding proposal accepted.
Test yourself and win! After each webinar, you can test what you have learned in a short multiple-choice questions challenge. With 10 or more successful tests, you will receive a small prize and a unique Nanofabrication Guru certificate.
