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…
Superintermolecular orbitals in the C/pentacene complex
G. P. Zhang, A. Gardner, T. Latta +2
We report a group of unusually big molecular orbitals in the C60/pentacene complex. Our first-principles density functional calculation shows that these orbitals are very delocaliz…
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…
Switching ferromagnetic spins by an ultrafast laser pulse: Emergence of giant optical spin-orbit torque
G. P. Zhang, Y. H. Bai, T. F. George
Faster magnetic recording technology is indispensable to massive data storage and big data sciences. {All-optical spin switching offers a possible solution}, but at present it is l…
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…
