Key concepts

Giant Magnetoresistance (GMR) — A quantum mechanical magnetoresistance effect observed in thin-film structures composed of alternating ferromagnetic and non-magnetic conducting layers, which exhibits a significant change in electrical resistance in…
Spin valve effect — A specific implementation of GMR where the resistance depends on the relative alignment of the magnetization of two ferromagnetic layers, separated by a non-magnetic conductive layer.
Nobel Prize in Physics (2007) — Awarded to Albert Fert and Peter Grünberg for their independent discovery of GMR, revolutionizing magnetic data storage.
Fundamental research — Scientific investigation aimed at increasing knowledge and understanding of basic principles, often without immediate commercial or practical applications in mind.
