Emergent anisotropy in magnetic metamaterials
Nanny Strandqvist, Björn Erik Skovdal, Merlin Pohlit +3
We demonstrate directional dependence of the self-modification of internal mesospin textures in magnetic metamaterials, arising from the coupling of the atomic- and mesoscopic leng…
Thermal excitations within and among mesospins in artificial spin ice
Björn Erik Skovdal, Samuel D. Slöetjes, Merlin Pohlit +3
We provide experimental and numerical evidence for thermal excitations within and among magnetic mesospins, forming artificial spin ice structures. At low temperatures, a decrease…
Temperature induced collapse of spin dimensionality in magnetic metamaterials
Björn Erik Skovdal, Nanny Strandqvist, Henry Stopfel +5
Spin and spatial dimensionalities are universal concepts, essential for describing both phase transitions and dynamics in magnetic materials. Lately, these ideas have been adopted…
Collective magnetic dynamics in artificial spin ice probed by AC susceptibility
Merlin Pohlit, Giuseppe Muscas, Ioan-Augustin Chioar +8
We report on the study of the thermal dynamics of square artificial spin ice, probed by means of temperature and frequency dependent AC susceptibility. Pronounced influence of the…
Direct-write of free-form 3D nanostructures with controlled magnetic frustration
Lukas Keller, Mohanad K. I. Al Mamoori, Jonathan Pieper +9
Building nanotechnological analogues of naturally occurring magnetic structures has proven to be a powerful approach to studying topics like geometry-induced magnetic frustration a…
Direct writing of CoFe alloy nanostructures by focused electron beam induced deposition from a heteronuclear precursor
F. Porrati, M. Pohlit, J. Muller +5
Recently, focused electron beam induced deposition has been employed to prepare functional magnetic nanostructures with potential in nanomagnetic logic and sensing applications by…
