Magnetic Metasurfaces and Superconducting Materials for Advanced Sensors and Spintronics
PhD Candidate: Aleix Barrera Català
Date: Wednesday, 2 July 2025 Time: 12.00 PM Venue: Institut de Ciència de Materials de Barcelona (ICMAB, CSIC) - Sala d'Actes Carles Miravitlles
Abstract
This study investigates magnetic metasurfaces composed of thin ferromagnetic films designed for magnetic flux concentration. To quantify magnetic enhancement and performance, various types of magnetic sensors based on anisotropic magnetoresistance were evaluated to optimize their operation within the magnetic flux concentrators. The results demonstrate significant magnetic enhancement potential, strongly influenced by metasurface design parameters such as thickness, size, and shape. Additionally, the study provides evidence of spin-orbit coupling in high-temperature superconductors, specifically YBCO, as revealed through magneto-transport measurements.
