Superconductors are materials with zero electrical resistivity and the ability to expel magnetic fields, which is known as the Meissner effect. Their dissipationless diamagnetic response is central to magnetic levitation and circuits such as quantum interference devices. In this work, we used superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves-collective spin excitations in magnets that are promising on-chip signal carriers-in a thin-film magnet.

It aims at measuring physical quantities with high resolution, sensitivity, and dynamic range. Electron spins in diamond are powerful magnetic field sensors, but their sensitivity in the microwave regime is limited to a narrow band around their resonance frequency.

Being able to image coherent spin-wave transport is crucial for developing interference-based spin-wave devices. We introduce magnetic resonance imaging of the microwave magnetic stray fields that are generated by spin waves as a new approach for imaging coherent spin-wave transport.

Thirty partially edentulous patients, having bilaterally 1 to 5 mm of residual bone height and at least 5 mm bone width below the maxillary sinuses as measured on computed tomography scans, were randomized to receive two 2-stage sinus lift procedures using the lateral window approach. On one side, the sinus lining the membrane was elevated with nasal suction technique and ultrasonic surgery approach, whereas on the contralateral side the membrane was elevated after osteotomy prepared using a round oral surgery bur.
