Unlocking ultrafast spin dynamics in a rare-earth magnet
Paul Herrgen, Christian Holzmann, Torben Manzke +5
The speed of optically driven magnetization dynamics is fundamentally determined by how efficiently angular momentum can be transferred between electronic, spin and lattice degrees…
Dynamic interfacial effects in ultrathin ferromagnetic bilayers
Anulekha De, Christopher Seibel, Sanjay Ashok +7
We investigate the magnetization dynamics of an ultrathin Co (1.5 nm) /Py (1.5 nm) bilayer system from femtosecond (fs) to nanosecond (ns) timescales. Magnetization dynamics in the…
Signatures of ballistic and diffusive transport in the time-dependent Kerr-response of magnetic materials
Sanjay Ashok, Jonas Hoefer, Martin Stiehl +4
We calculate the influence of diffusive and ballistic transport on ultrafast magnetization in thick metallic films. When only diffusive transport is present, gradients of magnetiza…
Driving Force of Ultrafast Magnetization Dynamics
Benedikt Y. Mueller, T. Roth, M. Cinchetti +2
Irradiating a ferromagnetic material with an ultrashort laser pulse leads to demagnetization on a femtosecond timescale. We implement Elliott-Yafet type spin-flip scattering, media…
Epitaxial film growth and magnetic properties of Co_2FeSi
H. Schneider, G. Jakob, M. Kallmayer +7
We have grown thin films of the Heusler compound Co_2FeSi by RF magnetron sputtering. On (100)-oriented MgO substrates we find fully epitaxial (100)-oriented and L2_1 ordered growt…
Spin-flip processes and ultrafast magnetization dynamics in Co - unifying the microscopic and macroscopic view of femtosecond magnetism
M. Cinchetti, M. Sánchez Albaneda, D. Hoffmann +7
The femtosecond magnetization dynamics of a thin cobalt film excited with ultrashort laser pulses has been studied using two complementary pump-probe techniques, namely spin-, ener…
