Density-Jump Transitions in the Debye-Hückel Theory of Spin Ice and Electrolytes
Omar J. Abbas, Steven T. Bramwell, Daan M. Arroo
Debye-Hückel theory, originally developed to describe dilute electrolyte solutions, has proved particularly successful as a description of magnetic monopoles in spin ice systems su…
Analytic Form of a Two-Dimensional Critical Distribution
Steven T. Bramwell
This paper explores the possibility of establishing an analytic form of the distribution of the order parameter fluctuations in a two-dimensional critical spin wave model, or width…
Experimental measurement of the isolated magnetic susceptibility
D. Billington, C. Paulsen, E. Lhotel +8
The isolated susceptibility may be defined as a (non-thermodynamic) average over the canonical ensemble, but while it has often been discussed in the literature, it has…
Tunable critical correlations in kagome ice
A. A. Turrini, A. Harman-Clarke, T. Fennell +4
We present a comprehensive experimental and theoretical study of the kagome ice Coulomb phase, that explores the fine tuning of critical correlations by applied field, temperature…
Experimental Measures of Topological Sector Fluctuations in the F-Model
Daan M. Arroo, Steven T. Bramwell
The two dimensional F-model is an ice-rule obeying model, with a low temperature antiferroelectric state and high temperature critical Coulomb phase. Polarization in the system is…
LiHoF: Cuboidal Demagnetizing Factor in an Ising Ferromagnet
Mikael Twengström, Laura Bovo, Oleg A. Petrenko +2
The demagnetizing factor has an important effect on the physics of ferromagnets. For cuboidal samples it depends on susceptibility and the historic problem of determining this func…
