Exchange striction determines how fast antiferromagnetic insulators demagnetize
Aleksandr Buzdakov, Ravi Kaushik, Nikolai Khokhlov +2
Antiferromagnets combine terahertz spin dynamics with insensitivity to stray fields, and how quickly their order can be manipulated sets the speed limit on device operation. Femtos…
Double-pulse control of all optical magnetization reversal in Tb/Co multilayers
Sheng Li, Dinar Khusyainov, Rein Liefferink +7
Recent experiments have shown that femtosecond laser pulse with a Gaussian intensity profile can induce magnetization reversal in Tb/Co multilayers with a ring-shaped switching pat…
X-ray View of Light-Induced Spin Reorientation in TmFeO: Direct Observation of a 90 Néel Vector Rotation
Somnath Jana, Ronny Knut, Dima Afanasiev +8
Using time-resolved X-ray magnetic linear dichroism in reflection, we provide a direct probe of the Néel vector dynamics in TmFeO on a ultrafast timescale. Our measurements rev…
Separating terahertz spin and charge contributions from ultrathin antiferromagnetic heterostructures
Thomas W. J. Metzger, Peter Fischer, Takashi Kikkawa +3
Femtosecond laser excitation of nanometer thin heterostructures comprising a heavy metal and a magnetically ordered material is known to result in the emission of terahertz radiati…
