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…

Tunable Enhancement of Magnetization Dynamics by Crystal Cut at Interface Exchange Coupled -FeO/NiFe Heterostructures
Hassan Al-Hamdo, Tobias Wagner, Philipp Schwenke +8
We investigate spin dynamics in -FeO/NiFe (Py) heterostructures, uncovering a robust mechanism for in-situ modulation of ferromagnetic resonance (FMR)…
