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…
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…
Impact of the crystal orientation on spin-orbit torques in Fe/Pd bilayers
Ankit Kumar, Nilamani Behera, Rahul Gupta +5
Spin-orbit torques in ferromagnetic (FM)/non-magnetic (NM) heterostructures offer more energy-efficient means to realize spin-logic devices; however, their strengths are determined…
