They are susceptible to the influence of the Weyl electrons, which push the Nd atom spins in a curious way.

Born to a glass cutter in North Bohemia, today a part of the Czech Republic, young Daniel Swarovski completed a two-year apprenticeship in his father's small factory. Chromium bromide (CrBr 3) is an insulator since chromium is trivalent and a bromine atom needs one electron to complete its outer shell.

The findings, which appear in Nature Materials, reveal a complex relationship among the material, the electrons flowing through it as current and the magnetism the material exhibits. Fundamentally, we might be able to create a variety of materials that have different internal spin characteristics — and perhaps we already have,” Broholm said.In other materials, such Weyl electrons have elicited new behaviors related to electrical conductivity.

Understanding the effects that the Weyl electrons drive also might shed light on other materials that have brought consternation to physicists. As discussed above, a fundamental rule of quantum mechanics, the Pauli exclusion principle, states that no two electrons with the same direction of spin can occupy the same point in space at the same time. Electrons are added one at a time to the d-states according to the empirical rule that the electrons arrange themselves in the state with the maximum spin and the maximum magnetic moment.
