Chiral nematic and fluctuation-induced first-order phase transitions in AB-stacked kagome bilayers
A. Zelenskiy, M. L. Plumer, B. W. Southern +2
We study a Heisenberg-Dzyaloshinskii-Moriya Hamiltonian on AB-stacked kagome bilayers at finite temperature. In a large portion of the parameter space, we observe three transitions…
Micromagnetic simulations of interacting dipoles on a fcc lattice: Application to nanoparticle assemblies
M L Plumer, J van Lierop, B W Southern +1
Micromagnetic simulations are used to examine the effects of cubic and axial anisotropy, magnetostatic interactions and temperature on M-H loops for a collection of magnetic dipole…
Monte Carlo Study of Maghemite Nanoparticles
K. Adebayo, B. W. Southern
We consider a simple model of maghemite nanoparticles and study their magnetic properties using Monte Carlo methods. The particles have a spherical geometry with diameters ranging…
Short-time dynamics of a family of XY noncollinear magnets
S. Bekhechi, B. W. Southern, A. Peles +1
Critical scaling and universality in the short-time dynamics for antiferromagnetic models on a three-dimensional stacked triangular lattice are investigated using Monte Carlo simul…
Critical properties of a continuous family of XY noncollinear magnets
A. Peles, B. W. Southern, B. Delamotte +2
Monte Carlo methods are used to study a family of three dimensional XY frustrated models interpolating continuously between the stacked triangular antiferromagnets and a variant of…
Frustrated Heisenberg Antiferromagnets between d=2 and d=3
A. Peles, B. W. Southern
The antiferromagnetic Heisenberg model on a stacked triangular geometry with a finite number of layers is studied using Monte Carlo methods. A topological phase transition occurs a…
