Internal talk - Off-set free magnetic sensing using spin-orbit torques: Principles and prototype characterization
Joshua Salazar-Mejía
IMS Nanofabrication

Feb. 29, 2024, 1 p.m.
This seminar is held in presence and online.
Room: HAL 115
Online: Zoom link of our Chair


Spin-current manipulation in spintronic devices has demonstrated tremendous potential for technological improvement of nowadays traditional electronic devices. Devices based on ferromagnet/heavy metal (FM/HM) interfaces and Spin-Orbit Torque (SOT) effects are deeply studied for sensing applications. Due to the high spin-orbit coupling of the heavy metal in such interfaces, current-induced SOTs can be employed to produce changes in the magnetization direction of the FM layer. The talk will focus on the design and analysis of a new magnetic sensor using Hall cross-shape and its importance in comparisson to previous models. Principles of micromagnetism for industrial applications will also be discussed.


Brief CV

Scientist and activist from Ecuador, he obtained his physics diploma working on Density Functional Theory studying Si(100)/CaF2 interfaces at Yachay Tech University in 2020. Current doctoral candidate from the Physik Funktioneller Materialen at Universitat Wien. During his doctoral studies, he research for novel sensing principles using micromagnetics, for speed sensing applications, research funded by Infineon. As an activist, founded the "OfflinePedia" volunteers project, to foster education in STEM through science communication festivals and donations of low-cost Linux computers in Ecuadorean rural communities. The effort of the volunteers has been awarded in Asia (Huawei), Europe (Falling Walls and Humboldt Foundations) and North America (MIT innovators U35), and it is currently being replicated in Mexico and Benin-Africa. Nowadays, he is working for IMS Nanofabrication, a semiconductors industry.
