Orientation-resolved ultrafast spin reorientation dynamics in ferrimagnetic DyCo
Johanna Richter, Martin Hennecke, Martin Schmidbauer +3
Under quasi-static conditions, ferrimagnetic DyCo thin films exhibit a thermally induced spin-reorientation transition, in which the equilibrium magnetization changes from an o…

Fluence dependent delay of Ni in an FeNi alloy supports an exchange based origin
Somnath Jana, Ronny Knut, Puloma Singh +9
The delayed demagnetization in Ni relative to Fe in the ultrafast demagnetization studies in FeNi alloy has led to two competing theoretical explanations: The Inhomogeneous Magnon…
