Ultrafast laser excitation of spin waves by permanent modification of the exchange bias interaction in IrMn/Co

TL;DR

This paper aimed to demonstrate ultrafast laser excitation of spin waves through permanent modification of exchange bias in IrMn/Co, but was withdrawn due to critical errors in key figures.

Contribution

The study proposed a novel method for ultrafast control of spin waves via laser-induced exchange bias modification, which was later retracted.

Findings

Initial evidence of laser-induced exchange bias change

Potential for ultrafast spin wave manipulation

Retraction due to data errors

Abstract

This paper has been withdrawn by the authors due to a critical error discovered in Figures 1, 2 and 4.
