Silicon spin qubits are promising for the realisation of scalable quantum computing platforms but their coherence times in natural silicon are limited by the non-zero nuclear spin of the ²⁹Si isotope. Here, enriched ²⁸ Si down to 2.3 ppm residual ²⁹Si is obtained by focused ion beam implantation.

Nonlinear memory devices such as memristors, memcapacitors, and meminductors, are the building blocks of energy-efficient neuromorphic computing. Here, the authors propose a superconducting circuit design acting as a microwave quantum memcapacitor, which could be implemented in neuromorphic quantum computing architectures.

The tetragonal tungsten bronzes are promising for high-temperature energy storage applications but the mechanisms for their broad dielectric responses are unclear. Here, a comprehensive experimental and theoretical study of Sr₂NaNb₅O₁₅ explains its two large dielectric anomalies in terms of structural transitions.

Ternary alloys of rare-earths and transition metals exhibit complex ferrimagnetic behavior as a function of alloy compositions. Here, X-ray magnetic circular dichroism of the Gd₆(Mn_1−xFe_x)₂₃ series is used to explain the composition dependence of sublattice Curie temperatures in terms of element-specific magnetic moment evolution.

Magnetic Josephson junctions are important for studying the interplay between superconductivity and ferromagnetism. Here, an inverse proximity effect with tunable nanoscale spin ordering at the superconductor/ferromagnet interface of Nb-permalloy structures is observed, confirming theoretical predictions on these systems.

Due to their plasmonic properties, silver nanoparticles are promising across a vast range of applications, from physics instrumentation to biomedicine and environmental science. Here, the photon-to-heat conversion efficiency of individual nanoparticles is elucidated by designing and fabricating an ultra-sensitive bolometer with 26 pW power resolution.

Adsorption has widely been studied in porous materials but the mechanism remains a mystery for nonporous systems. Now, nonporous polymeric crystals have been demonstrated to absorb molecules by coupling dynamic boron-nitrogen bonding and host-guest binding.
