Roughness density
Nirvana Caballero, Thierry Giamarchi
The theory of disordered elastic systems is one of the most powerful frameworks to assess the physics of multiple systems that span from ferromagnets to migrating biological cells.…
Dynamic response and roughening of ferroelectric domain walls driven at planar electrode edges
Guillaume Rapin, Sophia Ehrensperger, Cédric Blaser +2
Understanding and controlling the motion, stability, and equilibrium configuration of ferroelectric domain walls is key for their integration into potential nanoelectronics applica…
Microscopic interplay of temperature and disorder of a one-dimensional elastic interface
Nirvana Caballero, Thierry Giamarchi, Vivien Lecomte +1
Elastic interfaces display scale-invariant geometrical fluctuations at sufficiently large lengthscales. Their asymptotic static roughness then follows a power-law behavior, whose a…
Degradation of domains with sequential field application
Nirvana Caballero
Recent experiments show striking unexpected features when alternating square magnetic field pulses are applied to ferromagnetic samples: domains show area reduction and domains wal…
From bulk descriptions to emergent interfaces: connecting the Ginzburg-Landau and elastic line models
Nirvana Caballero, Elisabeth Agoritsas, Vivien Lecomte +1
Controlling interfaces is highly relevant from a technological point of view. However, their rich and complex behavior makes them very difficult to describe theoretically, and henc…
Tuning Ginzburg-Landau theory to quantitatively study thin ferromagnetic materials
Pamela C. Guruciaga, Nirvana Caballero, Vincent Jeudy +2
Along with experiments, numerical simulations are key to gaining insight into the underlying mechanisms governing domain wall motion in thin ferromagnetic systems. However, a direc…
Excess velocity of magnetic domain walls close to the depinning field
Nirvana B. Caballero, Iván Fernández Aguirre, Lucas J. Albornoz +8
Magnetic field driven domain wall velocities in [Co/Ni] based multilayers thin films have been measured using polar magneto-optic Kerr effect microscopy. The low field results are…
