Defect-mediated orientational ordering in stripe-forming magnetic systems
Premarun Barik, Johan van Lierop, Robert L. Stamps
We investigate the nonequilibrium development of orientational order in a two-dimensional stripe-forming magnetic system with competing interactions. Following a quench into the st…
Positive Temperature Coefficient of Anisotropy due to Groundstate in -FeO
Rachel Nickel, Kurt Kummer, Johan van Lierop
Positive anisotropy temperature coefficients () usually arise from hybridization between magnetic 3d states and strongly spin-orbit-coupled (SOC) subsystems. Yet -Fe$_2…
Active Inference Demonstrated with Artificial Spin Ice
Robert L. Stamps, Rehana Begum Popy, Johan van Lierop
A numerical model of interacting nanomagnetic elements is used to demonstrate active inference with a three dimensional Artificial Spin Ice structure. It is shown that thermal fluc…
Element-specific probe of quantum criticality in
A. Khansili, R. Sharma, R. Hissariya +11
Employing the elemental sensitivity of x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD), we study the valence and magnetic order in the heavy fermio…
Temperature and field evolution of site-dependent magnetism in -FeO nanoparticles
Richard Jones, Rachel Nickel, Palash K. Manna +2
8~nm epsilon-Fe2O3 nanoparticles exhibit a spin reorientation transition that begins at 150 K which is a hallmark of this unique iron-oxide polymorph. We find that the change from…
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…
