Thermodynamics of the SmCo5 compound doped with Fe and Ni: an ab initio study
A. Landa, P. Söderlind, D. Parker +7
SmCo5 permanent magnets exhibit enormous uniaxial magnetocrystalline anisotropy energy and have a high Curie temperature. However, a low energy product presents a significant drawb…
Prediction of a new efficient permanent magnet SmCoNiFe3
P. Söderlind, A. Landa, I. L. M. Locht +7
We propose a new efficient permanent magnet, SmCoNiFe3, that is a breakthrough development of the well-known SmCo5 prototype. More modern neodymium magnets of the Nd-Fe-B type have…
Phase transitions and spin-state of iron in FeO at the conditions of Earth's deep interior
E. Greenberg, R. Nazarov, A. Landa +8
Iron-bearing oxides undergo a series of pressure-induced electronic, spin and structural transitions that can cause seismic anomalies and dynamic instabilities in Earth's mantle an…
Analytic binary alloy volume-concentration relations and the deviation from Zen`s law
A. Landa, J. E. Klepeis, R. E. Rudd +2
Alloys expand or contract as concentrations change, and the resulting relationship between atomic volume and alloy content is an important property of the solid. While a well-known…
A large sub-Neptune transiting the thick-disk M4V TOI-2406
R. D. Wells, B. V. Rackham, N. Schanche +71
Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the large planet-to-star radius ratio…
