Even-Odd-Layer-Dependent Symmetry Breaking in Synthetic Antiferromagnets
Mitra Mani Subedi, Kuangyin Deng, Benedetta Flebus +1
In this work we examine synthetic antiferromagnetic structures consisting of two, three, and four antiferromagnetic coupled layers, i.e., bilayers, trilayers, and tetralayers. We v…
Evidence of Pseudogravitational Distortions of the Fermi Surface Geometry in the Antiferromagnetic Metal FeRh
Joseph Sklenar, Soho Shim, Hilal Saglam +6
The confluence between high-energy physics and condensed matter has produced groundbreaking results via unexpected connections between the two traditionally disparate areas. In thi…
Magnon-magnon interactions induced by spin pumping-driven symmetry breaking in synthetic antiferromagnets
Mitra Mani Subedi, Kuangyin Deng, Yuzan Xiong +9
The richness in both the dispersion and energy of antiferromagnetic magnons has spurred the magnetism community to consider antiferromagnets for future spintronic/magnonic applicat…
Hybrid magnonics for short-wavelength spin waves facilitated by a magnetic heterostructure
Jerad Inman, Yuzan Xiong, Rao Bidthanapally +8
Recent research on hybrid magnonics has been restricted by the long magnon wavelengths of the ferromagnetic resonance modes. We present an experiment on the hybridization of 250-nm…
Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
