Magn etic field sensors—in particular\, magnetoresistive (MR) sensors—were driven by the technological push from computers and information storage in the early 1990s.\n\nIn this talk\, Professor de Freitas will first introd uce key concepts in spintronics and highlight the physical mechanisms defi ning sensor performance and the figures of merit for the classification of outstanding MR sensors. The impressive technological progress in thin fil m preparation and characterization\, combined with nano- and microfabricat ion tools\, offer a large spectrum for device design. The materials discus sed include several varieties of thin films: oxide films as tunneling barr iers\, ultrathin amorphous and crystalline films\, ultrathin textured laye rs with grain size control\, magnetically soft layers\, and antiferromagne tic films\, all combined onto multilayer stacks\, typically thinner than 6 0 nm in total. In addition\, the noise mechanisms (the “killing factor ” that limits MR sensor performance) will be discussed\, and she will sh ow successful strategies for improving the signal-to-noise ratio\, which d etermines the ultimate field detectable by an MR sensor.\n\nExamples where spintronic sensors are useful tools for precision sensing will be provide d\, including integration with microfluidics\, optical\, and micro-electro mechanical micromachined actuators. Detection principles\, sensor design\, simulations\, and experimental validation will be discussed for exciting applications where MR sensors bring added value over competing technologie s. She will show how challenging applications have inspired creative solut ions\, requiring joint skills in physics\, materials\, electronics\, and m echanical engineering. Pr. de Freitas hopes that academics and engineers w ill be encouraged to propagate their expertise in magnetism to the young\, talented people we see every day\, and so promote innovation in future sp intronic sensors.\n\nSpeaker(s): Susana Cardoso de Freitas\, PhD\, \, \n\n Bldg: Quadrant\, 1120 Ringwood Ct.\, San Jose\, California\, United States \, 95131\, Virtual: https://events.vtools.ieee.org/m/355588 LOCATION:Bldg: Quadrant\, 1120 Ringwood Ct.\, San Jose\, California\, Unite d States\, 95131\, Virtual: https://events.vtools.ieee.org/m/355588 ORGANIZER:secretary@scvmag.org SEQUENCE:2 SUMMARY:Magnetic Sensors: From Ultrathin Film Growth to Sensor Integration in Unexpected Systems URL;VALUE=URI:https://events.vtools.ieee.org/m/355588 X-ALT-DESC:Description: <br /><h3>Hybrid Meeting<br />On-line and In Person at Quadrant</h3>\n<p>Refreshments will be available at Quadrant prior to the start of the presentation.</p>\n<p>Nanoelectronics combines physical p rinciples of materials with the impressive capability of engineering ultra -small devices at the nanoscale.
