Optically detected magnetic resonance of nitrogen-vacancy centers in microdiamonds inside nanopolycrystalline diamond anvil cell
Masahiro Ohkuma, Keigo Arai, Kenji Ohta +4
We demonstrated optically detected magnetic resonance (ODMR) of nitrogen-vacancy (NV) centers in microdiamonds inside a diamond anvil cell pressurized with nanopolycrystalline diam…
Absence of higher than 6-fold coordination in glassy up to 158 GPa revealed by X-ray absorption spectroscopy
João Elias F. S. Rodrigues, Angelika D. Rosa, Emin Mijit +5
Simple binary oxide glasses can exhibit a compression behavior distinct from that of their crystalline counterparts. In this study, we employed high-pressure X-ray absorption spect…
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…
Local electronic properties of La3Ni2O7 under pressure
Emin Mijit, Peiyue Ma, Christoph J. Sahle +14
The recent discovery of superconductivity in has attracted significant attention due to its high critical temperature and analogy to cuprate oxides. The oxidation…
