Phase-dependent parametric amplification of propagating spin waves in YIG nanostructures enabled by local inhomogeneities
Akira Lentfert, Ephraim Spindler, Björn Heinz +2
As magnonics evolves towards non-conventional computing, the development of phase-conserving and phase-sensitive amplification mechanisms becomes increasingly important. A particul…
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…
Magnetic nutation: transient separation of magnetization from its angular momentum
Anulekha De, Julius Schlegel, Akira Lentfert +6
For nearly 90 years, precession and relaxation processes have been thought to dominate magnetization dynamics. Only recently has it been considered that, on short time scales, an i…
Coherent and incoherent magnons induced by strong ultrafast demagnetization in thin permalloy films
Anulekha De, Akira Lentfert, Laura Scheuer +4
Understanding spin dynamics on femto- and picosecond timescales offers new opportunities for faster and more efficient spintronic devices. Here, we experimentally investigate the c…
Coherent magnetization dynamics in strongly quenched Ni thin films
Akira Lentfert, Anulekha De, Laura Scheuer +4
The remagnetization process after ultrafast demagnetization can be described by relaxation mechanisms between the spin, electron, and lattice reservoirs. Thereby, collective spin e…
Parametric generation of spin waves in nano-scaled magnonic conduits
Björn Heinz, Morteza Mohseni, Akira Lentfert +8
The research feld of magnonics proposes a low-energy wave-logic computation technology based on spin waves to complement the established CMOS technology and provide a basis for eme…
Long-range spin-wave propagation in transversely magnetized nano-scaled conduits
Björn Heinz, Qi Wang, Michael Schneider +8
Magnonics attracts increasing attention in the view of novel low-energy computation technologies based on spin waves. Recently, spin-wave propagation in longitudinally magnetized n…
