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…
Oscillatory Edge Modes in Two Dimensional Spin-Torque Oscillator Arrays
Shivam Kamboj, Rembert A. Duine, Benedetta Flebus +1
Spin torque oscillators (STOs) are dissipative magnetic systems that provide a natural platform for exploring non-Hermitian phenomena. We theoretically study a two-dimensional (2d)…
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…
Multitude of exceptional points in van der Waals magnets
Xin Li, Kuangyin Deng, Benedetta Flebus
Several works have recently addressed the emergence of exceptional points (EPs), i.e., spectral singularities of non-Hermitian Hamiltonians, in the long-wavelength dynamics of coup…
Topological magnetic phase transition in Eu-based A-type antiferromagnets
Eliot Heinrich, Thore Posske, Benedetta Flebus
Recently, a colossal magnetoresistance (CMR) was observed in EuCdP -- a compound that does not fit the conventional mixed-valence paradigm. Instead, experimental evidence p…
Exceptional points as signatures of dynamical magnetic phase transitions
Kuangyin Deng, Xin Li, Benedetta Flebus
One of the most fascinating and puzzling aspects of non-Hermitian systems is their spectral degeneracies, i.e., exceptional points (EPs), at which both eigenvalues and eigenvectors…
