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…
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…
Electrical transport measurements for superconducting sulfur hydrides using boron-doped diamond electrodes on beveled diamond anvil
Ryo Matsumoto, Mari Einaga, Shintaro Adachi +7
A diamond anvil cell (DAC) which can generate extremely high pressure of multi-megabar is promising tool to develop a further physics such a high-transition temperature superconduc…
Superconductivity of Pure H3S Synthesis from Elemental Sulfur and Hydrogen
Harushige Nakao, Mari Einaga, Masafumi Sakata +5
Superconductive H3S synthesized from H2S is very poorly crystallized, and has excess sulfur as impurity (3H2S -> 2H3S + S). The phase transition process undergoes in sulfur excess…
Superconducting Phase-Diagram of H3S under High Magnetic Fields
Shirin Mozaffari, Dan Sun, Vasily S. Minkov +7
We report the temperature dependence of the upper critical fields of the high temperature superconductor HS under applied pressures of 155 and 160 GPa through th…
Crystal Structure of 200 K-Superconducting Phase of Sulfur Hydride System
Mari Einaga, Masafumi Sakata, Takahiro Ishikawa +6
This article reports the experimentally clarified crystal structure of a recently discovered sulfur hydride in high temperature superconducting phase which has the highest critical…
Pressure-induced phase transition of Bi2Te3 into the bcc structure
Mari Einaga, Ayako Ohmura, Atsuko Nakayama +3
The pressure-induced phase transition of bismuth telluride, Bi2Te3, has been studied by synchrotron x-ray diffraction measurements at room temperature using a diamond-anvil cell (D…
