Boundary geometry controls a topological defect transition that determines lumen nucleation in embryonic development
Pamela C. Guruciaga, Takafumi Ichikawa, Steffen Plunder +2
Topological defects determine the collective properties of anisotropic materials. How their configurations are controlled is not well understood however, especially in 3D. In livin…
Field-dependent roughness of moving domain walls in a Pt/Co/Pt magnetic thin film
María José Cortés Burgos, Pamela C. Guruciaga, Daniel Jordán +5
The creep motion of domain walls driven by external fields in magnetic thin films is described by universal features related to the underlying depinning transition. One key paramet…
Dynamics and thermodynamics of a topological transition in spin ice materials under strain
L. Pili, A. Steppke, M. E. Barber +8
We study single crystals of DyTiO and HoTiO under magnetic field and stress applied along their [001] direction. We find that many of the features that the…
Domain-wall roughness in GdFeCo thin films: crossover length scales and roughness exponents
Lucas J. Albornoz, Pamela C. Guruciaga, Vincent Jeudy +2
Domain-wall dynamics and spatial fluctuations are closely related to each other and to universal features of disordered systems. Experimentally measured roughness exponents charact…
Fragmented monopole crystal, dimer entropy and Coulomb interactions in DyIrO
V. Cathelin, E. Lefrançois, J. Robert +12
Neutron scattering, specific heat and magnetisation measurements on both powders and single crystals reveal that DyIrO realizes the fragmented monopole crystal state in…
Anomalous out-of-equilibrium dynamics in the spin-ice material DyTiO under moderate magnetic fields
Pamela C. Guruciaga, Lucas Pili, Santiago Boyeras +3
We study experimentally and numerically the dynamics of the spin ice material DyTiO in the low temperature () and moderate magnetic field () regime ($T\i…
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…
Monte Carlo study on the detection of classical order by disorder in real antiferromagnetic Ising pyrochlores
Pamela C. Guruciaga, Rodolfo A. Borzi
We use Monte Carlo simulations to evaluate the feasibility of detecting thermal order by disorder in real antiferromagnetic Ising pyrochlores, frustrated by a magnetic field applie…
Field-tuned order by disorder in Ising frustrated magnets with antiferromagnetic interactions
Pamela C. Guruciaga, Marco Tarzia, M. Victoria Ferreyra +3
We demonstrate the appearance of thermal order by disorder in Ising pyrochlores with staggered antiferromagnetic order frustrated by an applied magnetic field. We use a mean-field…
Monopole ordered phases in dipolar and nearest-neighbours Ising pyrochlore: from spin ice to the "all-in--all-out" antiferromagnet
Pamela C. Guruciaga, Santiago A. Grigera, Rodolfo A. Borzi
We study Ising pyrochlores by means of Monte Carlo simulations. We cover a set of exchange constants ranging from the frustrated ferromagnetic case (spin-ice) to the fully-ordered…
