We report muon-spin rotation measurements of the pressure dependence of the oxygen-isotope (¹⁶O / ¹⁸O) effect on the spin-density wave (SDW) transition in the trilayer Ruddlesden-Popper nickelate Pr₄Ni₃O₁₀. At ambient pressure ...

We report zero-field (ZF) and transverse-field (TF) muon-spin rotation/relaxation (μSR) measurements on superconducting Li_0.95FeAs (T_c ≃ 16.0 K) grown by a high-pressure self-flux method. The ZF-μSR data show  ...

A muon-spin rotation/relaxation (µSR) study of the trilayer Ruddlesden–Popper nickelate Pr₄Ni₃O₁₀ was performed at ambient pressure and under hydrostatic pressure up to 2.2 GPa. Three magnetic transitions were identified ...

Researchers from Durham University and colleagues from Rutgers (The State University of New Jersey) and the University of Edinburgh have collaborated with teams from ISIS, the Institut Laue-Langevin (ILL) and the PSI Center for Neutron and Muon Sciences to carry out a full characterisation of the double perovskite Pb₂MgReO₆.

The observation of pressure-induced superconductivity in two- and three-layer Ruddlesden-Popper nickelates has spurred ...

In K(V_0.93Ta_0.07)₃Sb₅, Ta substitution suppresses charge order while nearly doubling superconducting transition temperature T_c. Pronounced diffuse scattering reveals a highly disordered charge-ordered state. We investigated the impact   ...

The thermodynamic critical field B_c provides direct access to the superconducting condensation energy, yet its pressure dependence has been studied much less extensively than that of the transition temperature. Here, muon-spin-rotation relaxation measurements ...

Demand for denser, lower-power data storage keeps rising, yet the metallic magnets behind most memory technologies dissipate energy through electrical currents. Magneto-electric insulators on the other hand offer an alternative...

The combination of localized magnetic moments, their frustration and interaction with itinerant electrons is a key challenge of condensed matter physics. Frustrated magnetic interactions ...

Metal−organic frameworks with coordinatively unsaturated metal sites (open metal sites) capable of engaging in orbital interactions with π-acidic gases are of interest for enabling ambient-temperature gas separations, such as hydrogen isotope separations. In view of the weakly π-acidic nature of H₂, we sought...

Magnetism in solid materials originates from tiny atomic “compasses” called electron spins. In many magnetically ordered compounds, these spins simply align parallel or antiparallel to each other. However, in more complex systems they can arrange into ...

Low-dimensional materials manifest structural anisotropy, quantum confinement, and tightly bound excitonic states, which make them attractive building blocks that can be assembled within three-dimensional laterally stitched heterostructures, stacked van der Waals solids, and complex moiré superlattices ...

EuAg₄Sb₂ is a rhombohedral europium triangular lattice material that exhibits a rich phase diagram of spin moiré superlattices (SMS) and single-q magnetic phases. In this paper, we characterize ...

We use muon spin rotation/relaxation/resonance (μSR) to investigate the magnetic properties of niobium pentoxide (Nb₂O₅) and tantalum pentoxide (Ta₂O₅) thin films. In both oxides, we observe a magnetic response at the lowest available temperature of 2.8 K ...

The steady decline of neutron imaging (NI) facilities—driven in part by the shutdown of several research reactors—has increased the need to maximize the use of existing infrastructure. In this context, a collaborative effort between PSI-CNM, PSI-NES, and EPFL-LRS has led to the development ...

Y-kapellasite [Y₃Cu₉(OH)₁₉Cl₈], which hosts an original anisotropic kagome sublattice, is a promising candidate for studying elusive and complex correlated physics. It exhibits a theoretically predicted in-plane (1/3; 1/3) magnetic order, but its magnetic interaction values place it close to a phase boundary to a spin liquid state ... 

The food industry is increasingly focusing on sustainable products. Proteins from green biomass are a promising option, as a research team involving the MLZ has discovered. These can be used, for example, as stabilisers in emulsions, such as in plant-based alternatives to yogurt, milk, ice cream, or cheese.

We report the dielectric and magnetic properties of epitaxial thin films of the high entropy oxide (HEO) perovskite Nd(Cr_0.2Mn_0.2Fe_0.2Co_0.2Ni_0.2)O₃, which orders magnetically below T_mag ≈ 190 K.
