High-pressure magnetic transition in iron observed via diamond quantum sensing
Kouki Yamamoto, Kenshin Uriu, Ryotaro Suda +5
Diamond quantum sensors offer high precision and spatial resolution as magnetic probes, making them promising for a wide range of applications. While diamond anvil cells (DACs) can…
Superhydrides on the way to ambient pressure: weak localization and persistent X-ray photoconductivity in BaSiH
Dmitrii V. Semenok, Di Zhou, Sven Luther +15
Reducing the stabilization pressure of superhydrides represents one of the most important challenges in hydrogen-saturated compound chemistry. Moving in this direction, we studied…
GPa Pressure Imaging Using Nanodiamond Quantum Sensors
Ryotaro Suda, Kenshin Uriu, Kouki Yamamoto +5
We demonstrate wide-field optical microscopy of the pressure distribution at approximately 20 GPa in a diamond anvil cell (DAC), using nitrogen-vacancy (NV) centers in nanodiamonds…
Enhancement of superconductivity on thin film of Sn under high pressure
Misaki Sasaki, Masahiro Ohkuma, Ryo Matsumoto +4
We investigated the pressure effects of a superconductivity on thin films of Sn. Elemental superconductor Sn with a body-centered tetragonal structure, -Sn, exhibits supercondu…
