Large effect of metal substrate on magnetic anisotropy of Co on hexagonal boron nitride

Harald Brune, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Fabio Donati, Aparajita Singha, Romana Baltic

We combine x-ray absorption spectroscopy (XAS), x-raymagnetic circular dichroism (XMCD) and x-ray magnetic linear dichroism (XMLD) data with first principles density functional theory (DFT) calculations and amultiorbital many-body Hamiltonian approach to u ...

Quantification of the local magnetized nanotube domains accelerating the photocatalytic removal of the emerging pollutant tetracycline

Henrik Moodysson Rønnow, Juan Kiwi, Ivica Zivkovic, Sami Rtimi, Jiajie Yu

( )Evidence is presented for the enhanced photodegradation of tetracycline (TC) by AgxO/FeOx/ZnO nanotubes (NTs) compared to AgxO/ZnO nanotubes under low-intensity solar light irradiation. A higher amount of the local magnetic domains with random orientati ...

Out-of-plane transport in ZrSiS and ZrSiSe microstructures

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer

A recent class of topological nodal-line semimetals with the general formula MSiX (M = Zr, Hf and X = S, Se, Te) has attracted much experimental and theoretical interest due to their properties, particularly their large magnetoresistances and high carrier ...

Bulk single-crystal growth of the theoretically predicted magnetic Weyl semimetals RAlGe (R = Pr, Ce)

Jonathan White, Neeraj Kumar

We explore two methods for single-crystal growth of the theoretically proposed magnetic Weyl semimetals RAlGe (R = Pr, Ce), which prove that a floating-zone technique, being both crucible- and flux-free, is crucial to obtain perfectly stoichiometric RAlGe ...

Unexpected Insights about Cation-Exchange on Metal Oxide Nanoparticles and Its Effect on Their Magnetic Behavior

Davide Deiana

Tuning the magnetic behavior of nanoparticles via the control of their features has always been challenging because these features are mostly intertwined. In the last years, a novel synthetic approach based on cation-exchange has been reported, and one of ...

Sr2Pt8−x As: a layered incommensurately modulated metal with saturated resistivity

László Forró, Oleg Yazyev, Alla Arakcheeva, Philip Johannes Walter Moll, Gabriel Albert Autes, Andrea Pisoni, Sergiy Katrych, Maja Deborah Bachmann, Edoardo Martino

The high-pressure synthesis and incommensurately modulated structure are reported for the new compound Sr2Pt8-xAs, with x = 0.715 (5). The structure consists of Sr2Pt3 As layers alternating with Pt-only corrugated grids. Ab initio calculations predict a me ...
