Angstrom-Scale Imaging of Magnetization in Antiferromagnetic FeAs via 4D-STEM
Kayla X. Nguyen, Jeffrey Huang, Manohar H. Karigerasi +6
We demonstrate a combination of computational tools and experimental 4D-STEM methods to image the local magnetic moment in antiferromagnetic FeAs with 6 angstrom spatial resolu…
High-resolution diffraction reveals magnetoelastic coupling and coherent phase separation in tetragonal CuMnAs
Manohar H. Karigerasi, Kisung Kang, Jeffrey Huang +6
Tetragonal CuMnAs was the first antiferromagnet where reorientation of the Néel vector was reported to occur by an inverse spin galvanic effect. A complicating factor in the format…
Synthesis of Eu(HCOO) and Eu(HCOO)(HCONH) crystals and observation of their DF transition for quantum information systems
Zachary W. Riedel, Donny R. Pearson, Manohar H. Karigerasi +3
Two stoichiometric metal-organic frameworks containing Eu cations are probed as candidates for photon-based quantum information storage. Synthesis procedures for growing 0.2…
Strongly two-dimensional exchange interactions in the in-plane metallic antiferromagnet FeAs probed by inelastic neutron scattering
Manohar H. Karigerasi, Kisung Kang, Garrett E. Granroth +3
To understand spin interactions in materials of the CuSb structure type, inelastic neutron scattering of FeAs single crystals was examined at different temperatures and inc…
Two-step magnetic ordering into a canted state in ferrimagnetic monoclinic MnAs
Manohar H Karigerasi, Bao H. Lam, Maxim Avdeev +1
We report the magnetic structure of room-temperature-stable, monoclinic MnAs at 3 K and 250 K using neutron powder diffraction measurements. From magnetometry data, the Cur…
Magnetocrystalline anisotropy of the easy-plane metallic antiferromagnet FeAs
Kexin Yang, Kisung Kang, Zhu Diao +4
Magnetocrystalline anisotropy is a fundamental property of magnetic materials that determines the dynamics of magnetic precession, the frequency of spin waves, the thermal stabilit…
An in-plane hexagonal antiferromagnet in the Cu-Mn-As system, CuMnAs
Manohar H. Karigerasi, Kisung Kang, Arun Ramanathan +5
We report the single-crystal growth and characterization of a new hexagonal phase, CuMnAs, in the Cu-Mn-As system. This compound contains the same square-pyramida…
Magneto-optic Response of the Metallic Antiferromagnet FeAs to Ultrafast Temperature Excursions
Kexin Yang, Kisung Kang, Zhu Diao +5
The linear magneto-optical Kerr effect (MOKE) is often used to probe magnetism of ferromagnetic materials, but MOKE cannot be applied to collinear antiferromagnets (AFs) due to the…
Uncovering anisotropic magnetic phases via fast dimensionality analysis
Manohar H. Karigerasi, Lucas K. Wagner, Daniel P. Shoemaker
A quantitative geometric predictor for the dimensionality of magnetic interactions is presented. This predictor is based on networks of superexchange interactions and can be quickl…
