Lanthanide Ion Electronic Structure Controls Magnetic Excitations in Topological Quantum Ferrimagnets (Ln = Tb, Dy, Ho)
Kelsey A. Collins, Jacob Pfund, Michael R. Page +3
The family of topological magnets is a promising platform for next-generation spintronic and magnonic technologies. However, the influence of the lanthanide ion ($…
Magneto Transport and Spin Reorientation in Pt Co78Ho22 Heterostructures Near the Sublattice Compensation Temperature
Rajeev Nepal, Jose Flores, Aurain Seaton +3
Metallic amorphous ferrimagnets of 3d transition metals (TM) and rare earths (RE) with 4f electrons exhibit rich magneto transport behavior due to the interplay between the 3d and…
Raman and Terahertz Spectroscopy of Low-Frequency Chiral Phonons in Amino Acids
Rahul Rao, Won Jin Choi, Joseph M. Slocik +6
Chiral phonons are mirror-symmetric vibrations that correspond to twisting and rotational motions of atoms. In chiral biomolecules, they correspond to low-energy terahertz (THz)-ra…
Ferroelectric Epsilon-WO3 Nanoparticles and Its Bipolaron Driven Opto-electronic Properties at Room Temperature
Mohammad M. Rahaman, Jose Flores, Mohamed Y. Noor +6
A unique polymorph of binary tungsten trioxide, the epsilon phase of WO3, has non-centrosymmetric ferroelectric structure, typically stable below -43 degree C in bulk. We have stab…
Electrical Side-Gate Control of Anisotropic Magnetoresistance and Magnetic Anisotropy in a Composite Multiferroic
Katherine Johnson, Michael Newburger, Michael Page +1
Composite multiferroics consisting of a ferroelectric material interfaced with a ferromagnetic material can function above room temperature and exhibit improved magnetoelectric (ME…
