ABSTRACT
Uniform magnetization precessions are generated by ultrafast optical excitation along the in-plane easy axis [100], as well as along the hard axis [1-10], in epitaxial Fe films grown on AlGaAs (001) over a wide range of applied magnetic fields. From the temporal evolution of the coherent magnetization precession, we determine the magnetic anisotropy constants and damping parameters which are crucial in designing fast magnetic switching devices and spintronics devices.

    Fast magnetization precession is observed in L10-FePt alloy epitaxial thin films excited and detected by all-optical means. The precession frequency varies from 45 to 65 GHz depending on the applied magnetic field strength and direction, which can be explained by a uniform precession model...

    Previous work has treated the diocotron mode for a low-energy beam and has found that any dissipative effect will cause this mode to grow. However, a treatment that considers the axial velocity of the beam shows that this mode will damp if the beam is relatively thin and the axial velocity of...

    The relationship between Gilbert damping and magneto-crystalline anisotropy is studied here using an all-optical method in a perpendicular Co/Ni multilayer system by varying the Ti-buffer thickness. As the Ti-buffer thickness increases, the magneto-crystalline anisotropy is enhanced. The...

    We report ferromagnetic resonance studies on linewidth of single crystal ultrathin Fe films on GaAs(100). For different orientations of the magnetic field in the film plane, anisotropic linewidth has been observed. An expression for anisotropy of linewidth with isotropic damping was derived and...

    In the present work we have studied the variation of LFMR as a function of the angle (θ) between the applied magnetic field and the plane of the film.

    We report on epitaxial growth and magnetic properties of Mn2.5Ga thin films, which were deposited on Cr/MgO single crystal substrates by magnetron sputtering. X-ray diffraction results revealed the epitaxial relationships as Mn2.5Ga(001)[100]∥Cr(001)[110]∥MgO(001)[100]. The presence of...

    The temperature dependence of the Gilbert damping and magnetic anisotropy are investigated in L21 Co2FeAl films epitaxially grown on GaAs (001) substrate by the time resolved magnetooptical Kerr effect.
