In frame of the International Research Seminars, the IN²UB organizes the specific:
Special Mini-symposium IN²UB, Profs. Guillem Aromí and Xavier Batlle, co-organizers
A new dawn for magnetism: from Spin Qubits to the spin-orbit based magnetic memory and terahertz generation.
15th July, 2022 – Aula magna Enric Casassas (Faculties of Chemistry and Physics)
[Registration required to know the capacity. Until July 7th]PROGRAM
10h-11h “Molecular Spin Qubits for Quantum Computer and Highly Density Memory Device Based on Molecular Magnets”. Prof. Masahiro Yamashita, Department of Chemistry, Graduate School of Science, Tohoku University. Chaired by Prof. Guillem Aromí – IN²UB Director.
As for molecular spin qubits, I will focus on the following three engineering methods: (1) crystal engineering method such as MOF spin qubits, (2) g-tensor engineering method, and (3) orbital engineering method”. As for highly density memory devices, I will focus on single-molecule memory device of TbPc2 SMM by using STM and STS. Then, I will focus on the negative magnetoresistance in SMMs encapsulated into SWCNT and metallic conducting SMMs by the interaction between conducting electron and localized SMMs.
11h-11.30h Coffee break
11.30-12.30h ‘Spin-orbit technologies: from magnetic memory to terahertz generation’. Prof. Hyunsoo Yang , Department of Electrical and Computer Engineering, National University of Singapore. Chaired by Prof. Xavier Batlle – IN²UB Steering Committee
Over the last decade, spintronic research has focused largely on techniques based on spin-orbit coupling, such as spin-orbit torques (SOTs), to alter the magnetic state. I will discuss the latest trends in SOT research, such as the exploration of novel material systems like topological materials and 2D materials to improve the SOT efficiency. Moving forward, I will introduce the process of terahertz generation in magnetic heterostructures, where the spin-orbit coupling phenomenon plays a dominant role. I will discuss the details of how this terahertz emission process can be extended to novel material systems such as ferrimagnets, topological materials, and 2D materials. The final section will focus on how the terahertz generation process can be used to measure the interrelation between terahertz generation and the SOTs, which are linked by the underlying spin-orbit coupling.
