Understanding all-optical spin switching: Comparison between experiment and theory
G. P. Zhang, M. Murakami, M. S. Si +2
Information technology depends on how one can control and manipulate signals accurately and quickly. Transistors are at the core of modern technology and are based on electron char…
First-principles and model simulation of all-optical spin reversal
G. P. Zhang, Z. Babyak, Y. Xue +2
All-optical spin switching is a potential trailblazer for information storage and communication at an unprecedented fast rate and free of magnetic fields. However, the current wisd…
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…
All-optical spin switching: A new frontier in femtomagnetism -- A short review and a simple theory
G. P. Zhang, T. Latta, Z. Babyak +2
Using an ultrafast laser pulse to manipulate the spin degree of freedom has broad technological appeal. It allows one to control the spin dynamics on a femtosecond time scale. The…
A new and simple model for magneto-optics uncovers an unexpected spin switching
G. P. Zhang, Y. H. Bai, Thomas F. George
In magneto-optics the spin angular momentum of a sample is indirectly probed by the rotation angle and ellipticity, which are mainly determined by the off-diagonal susceptibi…
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…
