Suppression of Thermal Conductivity via Singlet-Dominated Scattering in TmFeO
M. L. McLanahan, D. Lederman, A. P. Ramirez
We measured the thermal conductivity of the rare-earth orthoferrites, FeO, where = Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb from 3 K to 300 K and see an anomalous strong suppr…
Magnetoelectric properties of 500 nm Cr2O3 films
P. Borisov, T. Ashida, T. Nozaki +2
The linear magnetoelectric effect was measured in 500 nm Cr2O3 films grown by rf sputtering on Al2O3 substrates between top and bottom thin film Pt electrodes. Magnetoelectric susc…
Effects of hydrogen/deuterium absorption on the magnetic properties of Co/Pd multilayers
K. Munbodh, F. A. Perez, C. Keenan +3
The effects of hydrogen (H2) and deuterium (D2) absorption were studied in two Co/Pd multilayers with perpendicular magnetic anisotropy (PMA) using polarized neutron reflectivity (…
Coherent control of injection currents in high-quality films of Bi2Se3
D. A. Bas, K. Vargas-Velez, S. Babakiray +5
Films of the topological insulator Bi2Se3 are grown by molecular beam epitaxy with in-situ reflection high-energy electron diffraction. The films are shown to be high-quality by X-…
Order Parameter Criticality of the d=3 Random-Field Ising Antiferromagnet Fe(0.85)Zn(0.15)F2
F. Ye, L. Zhou, S. Larochelle +4
The critical exponent beta =0.16 +- 0.02 for the random-field Ising model order parameter is determined using extinction-free magnetic x-ray scattering for Fe(0.85)Zn(0.15)F2 in ma…
Geometric influence on the net magnetic moment in LaCoO thin films
T. Joshi, D. P. Belanger, Y. T. Tan +2
The different magnetic behaviors of LaCoO films grown on LaAlO and SrTiO are related to the Co-O-Co bond angles and the constraints imposed on the Co-O bond lengths by…
Altermagnetic and dipolar splitting of magnons in FeF
J. Sears, V. O. Garlea, D. Lederman +2
FeF is a prototypical rutile antiferromagnet recently proposed as an altermagnet, with a magnetic symmetry that permits spin-split electronic bands and chiral magnons. Using ve…
Engineered spatial inversion symmetry breaking in an oxide heterostructure built from isosymmetric room-temperature magnetically ordered components
J. Alaria, P. Borisov, M. S. Dyer +10
The oxide heterostructure [(YFeO)(LaFeO)], which is magnetically ordered and piezoelectric at room temperature, has been constructed from two weak ferromagne…
Epitaxial Stabilization and Emergent Charge Order in Copper Selenide Thin Films
B. M. Sharif, B. Theunissen, C. Westbrook +5
We demonstrate epitaxial growth of copper selenide (CuSe) thin films in both cubic and rhombohedral phases, achieved via molecular beam epitaxy on AlO (001) substra…
