Gauge theory applied to magnetic lattices
A. Di Pietro, P. Ansalone, V. Basso +2
Micromagnetic exchange is usually derived by performing the continuum limit of the Heisenberg model on a cubic lattice, where the exchange integrals are assumed to be identical for…
Bloch-to-Néel domain wall transition evinced through morphology of magnetic bubble expansion in Ta/CoFeB/MgO layers
Arianna Casiraghi, Alessandro Magni, Liza Herrera Diez +5
Ta/CoFeB/MgO trilayers with perpendicular magnetic anisotropy are often characterised by vanishing or modest values of interfacial Dzyaloshinskii-Moriya interaction (DMI), which re…
Magneto-optical imaging technique for hostile environment: the ghost imaging approach
A. Meda, A. Caprile, A. Avella +4
We develop a new approach in magneto-optical imaging (MOI), applying for the first time a ghost imaging (GI) protocol to perform Faraday microscopy. MOI is of the utmost importance…
Ground state optimization and hysteretic demagnetization: the random-field Ising model
Mikko J. Alava, Vittorio Basso, Francesca Colaiori +4
We compare the ground state of the random-field Ising model with Gaussian distributed random fields, with its non-equilibrium hysteretic counterpart, the demagnetized state. This i…
Phase transitions in a disordered system in and out of equilibrium
F. Colaiori, M. J. Alava, G. Durin +2
The equilibrium and non--equilibrium disorder induced phase transitions are compared in the random-field Ising model (RFIM). We identify in the demagnetized state (DS) the correct…
