Відкриття ефекту гігантського магнетоопору (ЕГМО)

Abstract

The report discusses the study of the giant magnetoresistance effect (GMRE) – one of the most important discoveries in solid-state physics of the late 20th century, which had a significant impact on the development of modern nanotechnology and spintronics. Its discovery made it possible to create a new generation of highly sensitive magnetoresistive sensors used in hard disk read heads. The report covers the history of the discovery of this phenomenon, its physical nature, experimental methods for its study and main characteristics. Special attention will be paid to the mechanism of spin-dependent electron scattering, which underlies GMRE.
