Nonlinear optical quantum theory of demagnetization in L1 FePt and FePd
G. P. Zhang, Y. H. Bai, Thomas F. George
It is now well established that a laser pulse can demagnetize a ferromagnet. However, for a long time, it has not had an analytic theory because it falls into neither nonlinear opt…
Gateway to all-optical spin switching in Heusler ferrimagnets: Pancharatnam-Berry tensor and magnetic moment ratio
G. P. Zhang, Y. Q. Liu, M. S. Si +4
All-optical spin switching (AOS) is a new phenomenon found in a small group of magnetic media, where a single laser pulse can switch spins from one direction to another, without as…
Ultrafast reduction of exchange splitting in ferromagnetic nickel
G. P. Zhang, Y. H. Bai, Thomas F. George
A decade ago Rhie \et (Phys. Rev. Lett. {\bf 90}, 247201 (2003)) reported that when ferromagnetic nickel is subject to an intense ultrashort laser pulse, its exchange splitting is…
Magnetic spin moment reduction in photoexcited ferromagnets through exchange interaction quenching: Beyond the rigid band approximation
G. P. Zhang, M. S. Si, Y. H. Bai +1
The exchange interaction among electrons is one of the most fundamental quantum mechanical interactions in nature and underlies any magnetic phenomena from ferromagnetic ordering t…
Laser-induced spin protection and switching in a specially designed magnetic dot: A theoretical investigation
G. P. Zhang, M. S. Si, T. F. George
Most laser-induced femtosecond magnetism investigations are done in magnetic thin films. Nanostructured magnetic dots, with their reduced dimensionality, present new opportunities…
