Magnetic monopole relaxation effects in spin ice DyTiO
Richard Edberg, Akash Khansili, Ingrid Marie Fjellvåg +5
Spin ice compounds enable the exploration of the dynamics of magnetic monopoles in condensed matter systems. In this study, we use ac calorimetry to probe the dynamical response of…
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…
Effects of uniaxial pressure on the spin ice Ho2Ti2O7
Richard Edberg, Ingrid Marie Bergh Bakke, Hirotaka Kondo +11
The spin ice materials Ho2Ti2O7 and Dy2Ti2O7 are experimental and theoretical exemplars of highly frustrated magnetic materials. However, the effects of an applied uniaxial pressur…
Emergent magnetic behaviour in the frustrated YbGaO garnet
Lise Orduk Sandberg, Richard Edberg, Kasper S. Pedersen +10
We report neutron scattering, magnetic susceptibility and Monte Carlo theoretical analysis to verify the short range nature of the magnetic structure and spin-spin correlations in…
Dipolar Spin Ice Under Uniaxial Pressure
Richard Edberg, Lise Ørduk Sandberg, Ingrid Marie Bergh Bakke +8
The magnetically frustrated spin ice family of materials is host to numerous exotic phenomena such as magnetic monopole excitations and macroscopic residual entropy extending to lo…
Effects of edge disorder in nano-scale antiferromagnetic clusters
Wanzhou Zhang, Wenan Guo, Kaj H Hoglund +2
We study the distribution of local magnetic susceptibilities in the two-dimensional antiferromagnetic S=1/2 Heisenberg model on various random clusters, in order to determine wheth…
