Cosmological signature change in Cartan gravity with dynamical symmetry breaking

Description: 18 pags.; 5 figs.; 3 apps. PACS numbers: 04.50.Kd , We investigate the possibility for classical metric signature change in a straightforward generalization of the first-order formulation of gravity, dubbed >Cartan gravity.> The mathematical structure of this theory mimics the electroweak theory in tha...

Magnetic transition in nanocrystalline soft magnetic alloys analyzed via ac inductive techniques

Description: The magnetic transition in a FeSiBCuNb nanocrystalline alloy, associated with the decoupling of ferromagnetic crystallites around the Curie point of the residual amorphous matrix, is analyzed in this work through the temperature dependence of the ac axial magnetic permeability and impedance of the s...

Resonant Raman scattering around the E0 transition of AlAs/InAs strained-layer superlattices

Description: We present an analysis of the resonant behavior of Raman scattering when exciting around the E0 transition of AlAs/InAs strained-layer superlattices grown on GaAs. To preserve the crystalline quality of the superlattices, the layers of InAs (well material) are kept at very low thicknesses while the ...

Phenomenological study of the amorphous Fe80B20 ferromagnet with small random anisotropy

Description: The magnetic behavior of some amorphous ferromagnets of composition Fe 80 − x R x B 20 (R being a rare-earth element) is investigated as a function of the external applied magnetic field and temperature using dc magnetic measurements. Random magnetic anisotropy is generated by dilution of rare-ear...

Pattern-induced magnetic anisotropy in FePt thin films by ion irradiation

Description: The magnetic properties of FePt thin films have been modified by exposing the samples to irradiation of 4 MeV Cl2+ ions. Patterned magnetic films, without modified topographical profile, were fabricated by irradiating the films through a shadowing micrometric mask. The structural changes, ascribed t...
