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…

We investigate spin dynamics in -FeO/NiFe (Py) heterostructures, uncovering a robust mechanism for in-situ modulation of ferromagnetic resonance (FMR)…
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…
Competing signatures of intersite and interlayer spin transfer in the ultrafast magnetization dynamics
