Temperature-dependent proximity magnetism in Pt

Temperature-dependent interface magnetism and magnetization reversal in Co/Pt multilayers

Relativity and Magnetism in Ni-Pd and Ni-Pt Alloys

We show that the differences in the magnetic properties of Ni-Pd and Ni-Pt alloys arise mainly due to relativity. In particular, we find that the local magnetic moment of Ni increases with the addition of Pd in Ni-Pd while it decreases with the addition of Pt in Ni-Pt, as found experimentally, only if relativity is present. Our analysis is based on the effects of relativity on (i) the spin-pola...

Proximity-induced magnetism in transition-metal substituted graphene

We investigate the interactions between two identical magnetic impurities substituted into a graphene superlattice. Using a first-principles approach, we calculate the electronic and magnetic properties for transition-metal substituted graphene systems with varying spatial separation. These calculations are compared for three different magnetic impurities, manganese, chromium, and vanadium. We ...

Temperature Difference Leads to Magnetism

Computer simulations suggest that creating hot and cold regions within a specific arrangement of semiconductors generates internal electric currents and magnetic fields. If borne out by experiments, the new effect, reported 8 July in Physical Review B, could lead to improvements in electronic devices that heat up in use. Experts are intrigued by the effect but remain cautious about its practica...

Unconventional temperature enhanced magnetism in Fe1.1Te.

Our inelastic neutron scattering study of spin excitations in iron telluride reveals remarkable thermal evolution of the collective magnetism. In the temperature range relevant for the superconductivity in FeTe(1-x)Se(x) materials, where the local-moment behavior is dominated by liquidlike correlations of emergent spin plaquettes, we observe unusual, marked increase of magnetic fluctuations upo...
