NONCOLLINEAR MAGNETIC ORDER IN THE DOUBLE PEROVSKITES: DOUBLE EXCHANGE ON A GEOMETRICALLY FRUSTRATED LATTICE
(2013)
Double perovskites (DPs) of the form A2BB′ O6 usually involve a transition metal ion, B, with a large magnetic moment, and a nonmagnetic ion B′. While many DPs are ferromagnetic, studies on the underlying model reveal the ...
Oxidation of W(110) studied by LEED and STM
(2010)
The oxidation of W(110) was studied over a temperature a range of 1000 K to 1600 K at 1x10-6 Torr oxygen. The subsequent oxide structure was then characterized using Low Energy Electron Di_raction (LEED) and Scanning ...
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, ...
Properties of lightweight fibrous structures made by a novel foam forming technique
(2019)
We describe a novel method for the production of lightweight fibrous structures of densities as low as 8.8 kg m−3
. The method is based on the use of liquid foam as a carrier medium for dispersed Kraft fibres. Different ...
The free-electron response in reflectance anisotropy spectra
(2006)
Reflectance anisotropy spectra (RAS), extended into the near infrared spectral region, of anisotropic metal islands, metal surfaces, and atomic nanowires are analyzed with respect to anisotropies in the optical response ...
Design of Slotted Single-Mode Lasers Suitable for Photonic Integration
(2010)
A single-mode laser structure suitable for photonic integration is presented. The laser can be fabricated by standard photolithography without any regrowth steps. Through optimization, a threshold current as low as 13 mA ...
Friedel Oscillations in graphene: Sublattice Asymmetry in Doping
(2013)
Symmetry breaking perturbations in an electronically conducting medium are known to produce Friedel oscillations in various physical quantities of an otherwise pristine material. Here we show in a mathematically transparent ...
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 ...
