Competing Jahn-Teller distortions combined with geometrical frustration give rise to a rich phase diagram as a function of x(Cu) and temperature in the spinel system Ni1-xCuxCr2O4. The Jahn-Teller distortion of the end members acts in opposite ways, with a ...
Double perovskite oxides A(2)BB'O-6 combining 3d and 4d or 5d transition metal ions at the B and B' sites feature a variety of magnetic and magneto-electric properties. Targeting Ba2FeOsO6, we synthesized powder samples of nonstoichiometric Ba2Fe1.12Os0.88 ...
The magnetic structure of the quasi-two-dimensional antiferromagnet NiPS3 has been determined by magnetometry and a variety of neutron diffraction techniques. The experiments show that the samples must be carefully handled, as gluing influences the magneto ...
Endogeneity is an important issue that often arises in discrete choice models leading to biased estimates of the parameters. We propose the extended multiple indicator solution (EMIS) methodology to correct for it and exemplify it with a case study using r ...
Here we show that it is possible to produce different magnetic core multiple shell heterostructures from monodisperse Fe3O4 spherical magnetic seeds by finely controlling the amount of a manganese precursor and using, in a smart and simple way, a cation-ex ...
We present a new, easily scalable method for the deposition of nanocrystalline hematite photoelectrodes based on the spin-coating of a mixed solution containing tin(II) and iron(III) chlorides followed by thermal treatment. Our facile approach does not req ...
The detection of cytosolic DNA by the sensor cGAS triggers potent antiviral responses. New data now propose that cGAS is regulated on a post-translational level by glutamylation. ...
We report on magnetic fluctuations studied by electron spin resonance (ESR) spectroscopy in the layered organic crystal ?-(BEDT-TTF)2Cu[N(CN)2]Cl. A line broadening above the antiferromagnetic ordering temperature, TN?=?23?K is attributed to two-dimensiona ...
A new copper selenite chloride Cu-5(SeO3)(4)Cl-2 has been prepared by chemical vapor transport reactions. Its crystal structure was determined by single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic space group P2(1)/c with t ...
Spin-wave resonances in pelletized powder of bismuth orthoferrite (BiFeO3) were studied in transmission spectroscopy at frequencies of 0.1–0.75 THz and in the temperature range of 300–650 K. A vector network analyzer with frequency extenders was used in co ...
