Anisotropy effects on the magnetic excitations of a ferromagnetic monolayer below and above the Curie temperature
M. G. Pini, P. Politi, R. L. Stamps
The field-driven reorientation transition of an anisotropic ferromagnetic monolayer is studied within the context of a finite-temperature Green's function theory. The equilibrium s…
Simultaneous existence of two spin-wave modes in ultrathin Fe/GaAs(001) films studied by Brillouin Light Scattering: experiment and theory
M. G. Pini, P. Politi, A. Rettori +4
A double-peaked structure was observed in the {\it in-situ} Brillouin Light Scattering (BLS) spectra of a 6 Å thick epitaxial Fe/GaAs(001) film for values of an external magneti…
Dipolar interaction between two-dimensional magnetic particles
Paolo Politi, Maria Gloria Pini
We determine the effective dipolar interaction between single domain two-dimensional ferromagnetic particles (islands or dots), taking into account their finite size. The first cor…
Absence of stable collinear configurations in Ni(001)ultrathin films: canted domain structure as ground state
G. Gubbiotti, G. Carlotti, M. G. Pini +5
Brillouin light scattering (BLS) measurements were performed for (17-120) Angstrom thick Cu/Ni/Cu/Si(001) films. A monotonic dependence of the frequency of the uniform mode on an i…
Shape anisotropy and magnetic domain structures in striped monolayers
Paolo Politi, Maria Gloria Pini
We study the effect of dipolar interactions on a magnetic striped monolayer with a microscopic unit cell of square symmetry, and of size spins. Even if the aspect…
