The Impact of Lattice Distortions on the Magnetic Stability of Single Atoms: Dy and Ho on BaO(100)

Harald Brune, Stefano Rusponi, Marina Pivetta, Boris Sorokin, Darius Constantin Merk, Sébastien Reynaud

X-ray magnetic circular dichroism, atomic multiplet simulations, and density functional theory calculations are employed to identify criteria for the optimum combination of supporting alkaline earth oxide and adsorption site maximizing the spin lifetimes o ...

A photonic integrated circuit-based erbium-doped amplifier

Tobias Kippenberg, Rui Ning Wang, Xinru Ji, Zheru Qiu, Junqiu Liu, Yang Liu, Jijun He, Anton Lukashchuk

Erbium-doped fiber amplifiers revolutionized long-haul optical communications and laser technology. Erbium ions could provide a basis for efficient optical amplification in photonic integrated circuits but their use remains impractical as a result of insuf ...

Gate Control of Spin-Layer-Locking FETs and Application to Monolayer LuIO

Nicola Marzari, Antimo Marrazzo, Thibault Daniel Pierre Sohier, Rong Zhang

A recent 2D spinFET concept proposes to switch electrostatically between two separate sublayers with strong and opposite intrinsic Rashba effects, exploiting the spin-layer-locking mechanism in centrosymmetric materials with local dipole fields. Here, we p ...

Unconventional Spin Relaxation Involving Localized Vibrational Modes in Ho Single-Atom Magnets

Harald Brune, Stefano Rusponi, Marina Pivetta, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha, Romana Baltic, Katharina Johanna Diller

We investigate the spin relaxation of Ho single atom magnets on MgO/Ag(100) as a function of temperature and magnetic field. We find that the spin relaxation is thermally activated at low field, while it remains larger than 1000 s up to 30 K and 8 T. This ...

Colorimetry of Luminescent Lanthanide Complexes

Anne-Sophie Chauvin, Julien Alexandre Andres

Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied. The conversion of spectral dat ...

Antiferromagnetic MnNi tips for spin-polarized scanning probe microscopy

Harald Brune, François Patthey, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Spin-polarized scanning tunneling microscopy (SP-STM) measures magnetoresistance with atomic resolution. While various methods for achieving SP probes have been developed, each is limited with respect to fabrication, performance, and operating conditions. ...

Photocatalytic Hydrogen Generation from a Visible-Light-Responsive Metal–Organic Framework System: Stability versus Activity of Molybdenum Sulfide Cocatalysts

Berend Smit, Andreas Züttel, Kyriakos Stylianou, Wen Luo, Daniele Ongari, Ngoc Tú Nguyên, Bardiya Valizadeh, Stavroula Kampouri, Ophélie Marie Planes

We report the use of two earth abundant molybdenum sulfide-based cocatalysts, Mo(3)S(13)(2-)clusters and 1T-MoS2 nanoparticles (NPs), in combination with the visible-light active metal-organic framework (MOF) MIL-125-NH2 for the photocatalytic generation o ...

A Smart Europium-Ruthenium Complex as Anticancer Prodrug: Controllable Drug Release and Real-Time Monitoring under Different Light Excitations

Jean-Claude Bünzli, Chen Xie

A unique, dual-function, photoactivatable anticancer prodrug, RuEuL, has been tailored that features a ruthenium(II) complex linked to a cyclen-europium chelate via a pi-conjugated bridge. Under irradiation at 488 nm, the dark-inactive prodrug undergoes ph ...

J1−J2 square-lattice Heisenberg antiferromagnets with 4d1 spins: AMoOPO4Cl (A=K,Rb)

Henrik Moodysson Rønnow, Peter Babkevich

Magnetic properties of AMoOPO4Cl (A=K,Rb) with Mo5+ ions in the 4d1 electronic configuration are investigated by magnetization, heat capacity, and nuclear magnetic resonance (NMR) measurements on single crystals, combined with powder neutron diffraction ex ...
