Observation of Scissors Modes in solid state systems with a SQUID
Keisuke Hatada, Kuniko Hayakawa, Fabrizio Palumbo +1
The occurrence of scissors modes in crystals that have deformed ions in their cells has been predicted some time ago. The theoretical value of their energy is rather uncertain, how…
A Two Rotor Model with spin for magnetic Nanoparticles
Keisuke Hatada, Kuniko Hayakawa, Augusto Marcelli +1
We argue that for some species of magnetic nanoparticles the macrospin can have a nonvanishing moment of inertia and then an orbital angular momentum. We represent such nanoparticl…
Scissors Modes: The elusive breathing overtone
Keisuke Hatada, Kuniko Hayakawa, Fabrizio Palumbo
The Two-Rotor Model predicts two levels above the Scissors Modes with degenerate intrinsic energy. They have and are referred to as overtones. Their energy is below…
Scissors Modes:The first overtone
Keisuke Hatada, Kuniko Hayakawa, Fabrizio Palumbo
Scissors modes were predicted in the framework of the Two-Rotor Model. This model has an intrinsic harmonic spectrum, so that the level above the Scissors Mode, the first overtone,…
Spin-Orbit Locking and Scissors Modes in rare earth crystals with uniaxial symmetry
Keisuke Hatada, Kuniko Hayakawa, Fabrizio Palumbo
A recent experiment has questioned the standard relative value of spin-orbit and crystal-field strengths in rare-earth electron systems, according to which the first should be…
Scissors modes in crystals with cubic symmetry
Keisuke Hatada, Kuniko Hayakawa, Fabrizio Palumbo
We recently suggested that the Scissors Mode (a collective excitation in which one system rotates with respect another one conserving its shape) can occur in crystals with axially…
