The SOTQuInt Project submitted a digest for oral presentation to the Intermag 2026 conference in Manchester from 13-17 April. The results on the Spin Seebeck effect in Tm substituted YIG samples will be presented.
From November 25 to 26, 2025, Prof. Hans Hug (EMPA, Switzerland) visited INRiM and a seminar and trainings session on quantitative MFM measurements were organized. MSc. Simran Sahoo attended the trainings session.
From November 25 to December 20 2025 the PhD student Simran Sahoo is taking a trainings period at INRiM. The training includes MOKE, MFM and thermomagnetic and magnetoresistive measurements.
From November 18 to 19 2025 a joint workshop on "Emergent Magnetic Storage Devices and Sensors" was held at SMST, IIT (BHU). This joint Indo-Italy workshop brought together leading researchers, scientists, and industry experts from India and Italy to discuss cutting-edge developments in emergent magnetic storage devices and sensors.
The members of the research team INRiM, Vittorio Basso and Alessandro Magni, together with the PI Michaela Kuepferling visited the laboratories at SMST, IIT (BHU), Varanasi, from November 14 to 23 2025. The outcome of the ongoing work of the first project year was discussed and future plans for the upcoming years were established.
First online project meeting on May 29 2025! Presentations uploaded on the sharepoint.
The project was selected on April 10 2025 and the first year's funding granted on May 14 2025!
The general objective of this project is to determine the role of interfacial interdiffusion on Spin-Orbit Torque (SOT) in heterostructures composed of Quantum Materials (QM)/Ferromagnetic Metal (FM) and QM/Ferrimagnetic Oxide (FO). These nanodevices are very promising for memories and logic based on magnetic domain walls (DWs). The interface and crystallographic structure are crucial for designing efficient SOT-based devices.
The objectives for the first year are to lay the groundwork for the project's first two main goals:
Explore the SOT mechanism in QM/FM and QM/FO heterostructures: The contributions of the Rashba effect and the spin-Hall effect to SOT will be quantified, and its temperature dependence will be determined.
Optimize SOT-induced DW motion: This will involve analyzing how SOT in these heterostructures can be used to control magnetization and how such control can be optimized.
Specifically, the first year will focus on the growth of magnetic heterostructures and the characterization of their structural and interfacial properties (IIT responsibility), as well as magnetic characterization using the magneto-optical Kerr effect (MOKE) and a vibrating sample magnetometer (SQUID-VSM) (INRiM responsibility). Furthermore, on the Italian side, the experimental setups for SOT and MOKE will be updated and prepared for the second year's activities.
