Imaging and identification of point defects in PtTe2
(2021)
The properties and performance of two-dimensional (2D) materials can be greatly affected by point defects. PtTe2, a 2D material
that belongs to the group 10 transition metal dichalcogenides, is a type-II Dirac semimetal, ...
Magnetic order and magnetotransport in half-metallic ferrimagnetic MnyRuxGa thin films
(2021)
The ruthenium content of half-metallic Mn2RuxGa thin films, with a biaxially strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic and electronic properties. An extensive study of ...
Ultrafast Double Pulse All-Optical Reswitching of a Ferrimagnet
(2021)
All-optical reswitching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effect of a second 200 fs, 800 nm laser pulse ...
Pauli paramagnetism of cubic V3Al, CrVTiAl, and related 18-electron Heusler compounds with a group-13 element
(2021)
Calculations suggest that ordered Heusler alloys with 18 valance electrons could exhibit a variety of unusual electronic and magnetic states that are absent in the constituent elements. They include magnetic semiconductors, ...
Magnetic control over the fractal dimension of supramolecular rod networks
(2021)
Controlling supramolecular polymerization is of fundamental importance to create advanced materials and devices. Here we show that the thermodynamic equilibrium of Gd3+-bearing supramolecular rod networks is shifted ...
Exfoliation of hematite: Morphological, structural and magnetic investigations
(2022)
Three natural specimens of hematite are characterized using X-ray diffraction, magnetometry, IR/Raman and Mössbauer spectroscopy, with focus on the Morin transition. All are exfoliated by grinding and prolonged sonication ...
Imaging domains in a zero-moment half-metal
(2019)
We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromagnets or compensated ferrimagnets, which ...
