Helicity-dependent optical control of the magnetization state emerging from the Landau-Lifshitz-Gilbert equation
Benjamin Assouline, Amir Capua
It is well known that the Gilbert relaxation time of a magnetic moment scales inversely with the magnitude of the externally applied field, H, and the Gilbert damping, α. Therefore…
The Ferris ferromagnetic resonance technique: principles and applications
Amit Rothschild, Benjamin Assouline, Nadav Am Shalom +4
Measurements of ferromagnetic resonance (FMR) are pivotal to modern magnetism and spintronics. Recently, we reported on the Ferris FMR technique, which relies on large-amplitude mo…
Efficient generation of spin currents by the Orbital Hall effect in pure Cu and Al and their measurement by a Ferris-wheel ferromagnetic resonance technique at the wafer level
Amit Rothschild, Nadav Am-Shalom, Nirel Bernstein +7
We present a new ferromagnetic resonance (FMR) method that we term the Ferris FMR. It is wideband, has significantly higher sensitivity as compared to conventional FMR systems, and…
Magnetization dynamics in the density matrix formalism
Benjamin Assouline, Amir Capua
Magnetization dynamics described by the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can be formulated to have the form of the well-known two-level-system (TLS) equations. R…
Spin-current amplification by stimulated spin pumping
Benjamin Assouline, Marina Brik, Nirel Bernstein +1
Stimulated emission is a process during which an atomic system gives away energy to create a coherent photon. It is fundamental to the operation of the optical amplifier. Here we p…
Determination of the spin Hall angle by the inverse spin Hall effect, device level ferromagnetic resonance, and spin torque ferromagnetic resonance: a comparison of methods
Ranen Ben-Shalom, Nirel Bernstein, See-Hun Yang +1
The spin torque ferromagnetic resonance (STFMR) is one of the popular methods for measurement of the spin Hall angle (SHA). However, in order to accurately determine SHA from STFMR…
Microwave and spin transfer torque driven coherent control in ferromagnets
Marina Brik, Nirel Bernstein, Amir Capua
Coherent control is a method used to manipulate the state of matter using oscillatory electromagnetic radiation which relies on the non-adiabatic interaction. It is commonly applie…
Classical limit of Rabi nutations in spins of ferromagnets
Amir Capua, Charles Rettner, See-Hun Yang +1
Rabi oscillations describe the interaction of a two-level system with a rotating electromagnetic field. As such, they serve as the principle method for manipulating quantum bits. B…
Determination of intrinsic damping of perpendicularly magnetized ultrathin films from time resolved precessional magnetization measurements
Amir Capua, See-hun Yang, Timothy Phung +1
Magnetization dynamics are strongly influenced by damping. An effective damping constant αeff is often determined experimentally from the spectral linewidth of the free induction d…
Electron wavefunction probing in room-temperature semiconductors: direct observation of Rabi oscillations and self-induced transparency
Amir Capua, Ouri Karni, Gadi Eisenstein +1
Quantum coherent light-matter interactions have been at the forefront of scientific interest since the fundamental predictions of Einstein and the later work of Rabi. Direct observ…
