Conductivity of electronic liquid-crystalline mesophases
Rafael M. Fernandes, Jörg Schmalian, Harry Westfahl
We investigate the connection between the transport properties and the thermodynamics of electronic systems with a tendency to form broken-symmetry mesophases evocative of the phys…
Driven dissipative dynamics of spins in quantum dots
Frederico Brito, Harry Westfahl, Amir O. Caldeira +1
We have studied the dissipative dynamics of a driven electronic spin trapped in a quantum dot. We consider the dissipative mechanism as due to the indirect coupling of the electron…
Magnetic structure and critical behavior of GdRhIn: resonant x-ray diffraction and renormalization group analysis
E. Granado, B. Uchoa, A. Malachias +3
The magnetic structure and fluctuations of tetragonal GdRhIn5 were studied by resonant x-ray diffraction at the Gd LII and LIII edges, followed by a renormalization group analysis…
Fluctuation induced first-order phase transitions in a dipolar Ising ferromagnet slab
Rafael M. Fernandes, Harry Westfahl
We investigate the competition between the dipolar and the exchange interaction in a ferromagnetic slab with finite thickness and finite width. From an analytical approximate expre…
Magnetic reconfiguration of MnAs/GaAs(001) observed by Magnetic Force Microscopy and Resonant Soft X-ray Scattering
L. N. Coelho, R. Magalhães-Paniago, B. R. A. Neves +7
We investigated the thermal evolution of the magnetic properties of MnAs epitaxial films grown on GaAs(001) during the coexistence of hexagonal/orthorhombic phases using polarized…
Domain wall formation and spin reorientation in finite-size magnetic systems
Rafael M. Fernandes, Harry Westfahl, Rogério Magalhães-Paniago +1
We investigate the formation of stable one-dimensional Néel walls in a ferromagnetic slab with finite thickness and finite width. Taking into account the dipolar, the exchange and…
