The use of methane as a reactive gas dramatically increases the selectivity arc-discharge synthesis M-Ti-carbide clusterfullerenes (M=Y, Nd, Gd, Dy, Er, Lu). Optimization process parameters allows Dy2TiC@C80-I and its facile isolation in single chromatographic step. A new type cluster with an endohedral acetylide unit, M2TiC2@C80, is discovered along second isomer M2TiC@C80. Dy2TiC@C80-(I,II) Dy2TiC2@C80-I are shown to be single-molecule magnets (SMM), but presence carbon atom Dy2TiC2@C80...
Endohedral metallofullerenes with nitride clusters DySc<sub>2</sub>N and Dy<sub>2</sub>ScN encapsulated in different carbon cages behave as single molecule magnets (SMMs) strongly cage-dependent SMM parameters.

The anomalous magnetic moment of the muon is one most precisely measured quantities in experimental particle physics. Its latest measurement at Brookhaven National Laboratory deviates from Standard Model expectation by approximately 3.5 standard deviations. goal new experiment, E989, now under construction Fermilab, a fourfold improvement precision. Here, we discuss details future and its current status.
The impact of the second metal on synthesis and molecular structure Dy–M nitride clusterfullerenes (M = Gd, Er, Tm, Lu) is evaluated systematically.

Abstract Methan erhöht als reaktives Gas drastisch die Selektivität der Lichtbogensynthese von M‐Ti‐Carbidclusterfullerenen (M=Y, Nd, Gd, Dy, Er, Lu). Ferner ermöglicht Optimierung Prozessparameter Synthese Dy 2 TiC@C 80 ‐I und dessen einfache Isolierung in einem einzigen chromatographischen Schritt. Neben zweiten Isomer des M wurde außerdem eine neue Clusterart mit endohedraler Acetylidgruppe, TiC @C , entdeckt. Weiterhin wirken ‐(I,II) Einzelmolekülmagenten (SMMs), jedoch verschlechtert...
A key parameter for the low-temperature magnetic coupling of in dinuclear lanthanide single-molecule magnets (SMMs) is barrier ${U}_{FA}$ resulting from exchange and dipole interactions between two $4f$ moments. Here we extend pseudospin model previously used to describe ground state endofullerenes account variations orientation single-ion anisotropy axes apply it SMMs ${\mathrm{Dy}}_{2}\mathrm{ScN}$@${\mathrm{C}}_{80}$ ${\mathrm{Dy}}_{2}\mathrm{TiC}$@${\mathrm{C}}_{80}$. While x-ray...
Endohedral fullerenes are perfect nanolaboratories for the study of magnetism. The substitution a diamagnetic scandium atom in Dy2ScN@C80 with gadolinium decreases stability given magnetization and demonstrates Gd to act as single catalyst that accelerates reaching thermal equilibrium. X-ray magnetic circular dichroism at M4,5 edges Dy shows moment follows sum external dipolar field two ions compared lower exchange barrier is found between ferromagnetic antiferromagnetic configuration....
Endohedral lanthanide ions packed inside carbon nanotubes (CNTs) in a one-dimensional assembly have been studied with combination of high resolution transmission electron microscopy (HRTEM), scanning x-ray (STXM), and magnetic circular dichroism (XMCD). By correlating HRTEM STXM images we show that structures down to 30 nm are resolved chemical contrast record absorption spectra from endohedral embedded individual nanoscale CNT bundles. XMCD measurements an Er3N@C80 bulk sample macroscopic...
