Centennial Nobel
GMR Teaching & Research System
The 2007 Nobel Prize in Physics was awarded to French scientist Albert Fert and German scientist Peter Grünberg for their independent discovery of Giant Magnetoresistance (GMR).
The Giant Magnetoresistance (GMR) Teaching & Research System, independently developed by Jiuzhang Quantum, builds upon classic experimental instruments by incorporating a variety of new GMR sensors and offering open circuit designs. This allows students to explore the principles and practical applications of different GMR effects. Equipped with self-developed wireless voltage sensors and data acquisition/processing software, the system makes physics experiments more convenient and efficient. Combined with Jiuzhang’s comprehensive turnkey solutions, it effectively enhances students' overall scientific research capabilities.
