LaFeAsO1-xHx is a prototypical iron-based superconductor. However, its phase diagram presents unique properties compared to conventional iron-based superconductors: (1) the superconducting phase is sandwiched between two antiferromagnetic (AF) phases

FeSe1-xSx has attracted much attention among iron-based superconductors because the pure sample undergoes nematic and superconducting (SC) phase transitions without magnetism. A pressure-induced antiferromagnetic (AFM) phase emerges upon applying pre

FeSe is a unique high-$$T_c$$ T c iron-based superconductor in which nematicity, superconductivity, and magnetism are entangled with each other in the P-T phase diagram. We performed $$^{77}$$ 77 Se-nuclear magnetic resonance measurements under press

A “palm” cubic-anvil pressure cell (PCAC) having an outer diameter of 60 mm, the smallest cubic-anvil cell to date, was fabricated to insert in a large-bore superconducting magnet. The pressure cell has a sample space of ϕ 2.5 × 1.5 mm^2, which

A prototypical electron-doped iron-based superconductor $LaFeAsO_{1-x}H_x$ undergoes an antiferromagnetic (AF) phase for $x \geq 0.49$. We performed NMR measurements on $LaFeAsO_{0.4}H_{0.6}$ at 3.7 GPa to investigate the magnetic properties in the v

We performed [Formula: see text]-nuclear magnetic resonance measurements on [Formula: see text] ([Formula: see text] = 0.12 and 0.23). We found from the relaxation time [Formula: see text] that nematicity and antiferromagnetic fluctuations show coope
