Three-dimensional phase-field study of grain coarsening and grain shape accommodation in the final stage of liquid-phase sintering

Liesbeth Maria L Vanherpe

A 3-dimensional phase-field model is implemented to simulate the grain evolution in the final stage of liquid-phase sintering. The model considers a liquid phase and a polycrystalline solid phase. Results for varying ratios of the solid-solid interface ene ...

Device and methods for shell phase removal of core-shell capsules

Esther Amstad, Antoine Claude Jean Vian

A device and method for the mechanical (partial or total) removal of the liquid phase of the external shell of a core-shell capsule is disclosed. The device comprises a main channel having at least one inlet, one outlet and a tubular element in between, ad ...

Magnetic Skyrmions and Skyrmion Clusters in the Helical Phase of Cu2OSeO3

Henrik Moodysson Rønnow, Fabrizio Carbone, Ping Huang, Yoshie Murooka

Skyrmions are nanometric spin whirls that can be stabilized in magnets lacking inversion symmetry. The properties of isolated Skyrmions embedded in a ferromagnetic background have been intensively studied. We show that single Skyrmions and clusters of Skyr ...

Topological Aspects of Symmetry Breaking in Triangular-Lattice Ising Antiferromagnets

Frédéric Mila, Andrew James Smerald

Using a specially designed Monte Carlo algorithm with directed loops, we investigate the triangular lattice Ising antiferromagnet with coupling beyond the nearest neighbors. We show that the first-order transition from the stripe state to the paramagnet ca ...

Magnetization dynamics of topological defects and the spin solid in a kagome artificial spin ice

Dirk Grundler, Vinayak Shantaram Bhat

We report broadband spin-wave spectroscopy on kagome artificial spin ice (ASI) made of large arrays of interconnected Ni 80 Fe 20 nanobars. Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic magnetic field d ...

Two-Dimensional Nanoparticle Supracrystals: A Model System for Two-Dimensional Melting

Francesco Stellacci, Jiwon Kim

In a Langmuir trough, successive compression cycles can drive a two-dimensional (2D) nanoparticle supracrystal (NPSC) closer to its equilibrium structure. Here, we show a series of equilibrated 2D NPSCs consisting of gold NPs of uniform size, varying solel ...

Dimensional Reduction in Quantum Dipolar Antiferromagnets

Henrik Moodysson Rønnow, Martin Mansson, Peter Babkevich, Ivan Kovacevic

We report ac susceptibility, specific heat, and neutron scattering measurements on a dipolar-coupled antiferromagnet LiYbF4. For the thermal transition, the order-parameter critical exponent is found to be 0.20(1) and the specific-heat critical exponent -0 ...

Modeling of percolation of globular-equiaxed grains in Al-Cu alloys

Michel Rappaz, Jean-Luc Desbiolles, Christophe Mondoux

A new mesoscopic model able to describe percolation of globular-equiaxed grains, highly relevant for hot tearing formation in castings, has been developed. This model is inspired from the granular model of Sistaninia et al. [1-5] that considers polyhedral ...
