And indeed, he was right: not only birds, but a multitude of other species also possess a magnetic sixth sense. However, three quarters of a century later there are still many unknowns; one of them, perhaps the most intriguing, is whether we humans also have this ability without knowing it. When Von Frisch proposed in 1927 that the dance of ...
Abstract. Magnets composed of molecular components that provide both electron spins and spin-coupling pathways can stabilize bulk magnetic ordering. This was first reported for the ionic, zero-dimensional (0-D) electron transfer salt [Fe (C 5 Me 5) 2] + [TCNE]˙ − (TCNE = tetracyanoethylene ), which orders as a ferromagnet at Tc = 4.8 K.
The magnetic ordering momentums (wave vectors) are the momentums at which the spin structural factor diverges (in the thermodynamic limit).. Let $mathbf{S}(mathbf{r})$ be the spin operator at position $mathbf{r}$ in the material, the spin structural factor is defined as the Fourier transformation of the spin-spin correlation …

As kids, we all learned that people have five senses: sight, sound, smell, touch, and taste. But the truth is that we've got all kinds of perceptive abilities. We can feel pain, and the passing ...
High spin Mn 2+ has long been considered as a model ion for the study of the magnetic behavior, 29,30 most clearly illustrated in the rock salt structured fcc lattice of MnO that provided the first demonstration 31 of long-range antiferromagnetic type ordering of spins as predicted by Néel. 32,33 The behavior of Mn 2+ on fcc lattices has ...

To find out, we built an experimental chamber to apply a controlled magnetic field, then used electroencephalography (EEG) to test humans for brain responses to field changes. EEG records brain electrical activity and reflects information processing in many …
The most common magnetic ordering in insulating TLAFs is the 120° structure. However, a new triple-Q chiral ordering can emerge in metallic TLAFs, representing the short wavelength limit of ...
In this chapter, the nature of magnetic ordering in cobalt‐based spinels Co3O4, Co2SnO4, Co2TiO4, and Co2MnO4 is reviewed, and some new results that have not been reported before are presented. A systematic comparative analysis of various results available in the literature is presented with a focus on how occupation of the …
We find that at the mean-field level, these rotationally invariant models naturally support a noncoplanar chiral magnetic ordering. It appears as a weak-coupling instability at the band filling factor 3/4 due to the perfect nesting of the itinerant electron Fermi surface. This ordering is a triangular-lattice counterpart of the collinear Neel ...
Abstract. Density-functional calculations are carried out to investigate incommensurate magnetic structures and ferroelectric polarization in the newly discovered multiferroic material MnI 2.
