Open AccessDiscovery of conjoined charge density waves in the kagome superconductor CsV3Sb5
The electronic instabilities in CsV3Sb5 are believed to originate from the V 3d-electrons on the kagome plane, however the role of Sb 5p-electrons for 3-dimensional orders is largely unexplored. Here, using reson...

Open AccessPressure-induced monotonic enhancement of Tc to over 30 K in superconducting Pr0.82Sr0.18NiO2 thin films
The successful synthesis of superconducting infinite-layer nickelate thin films with the highest Tc ≈ 15 K has ignited great enthusiasm for this material class as potential analogs of the high-Tc cuprates. Pursui...

Open AccessPressured-induced superconducting phase with large upper critical field and concomitant enhancement of antiferromagnetic transition in EuTe2
We report an unusual pressure-induced superconducting state that coexists with an antiferromagnetic ordering of Eu2+ moments and shows a large upper critical field comparable to the Pauli paramagnetic limit in Eu...

Open AccessQuasi-one-dimensional superconductivity in the pressurized charge-density-wave conductor HfTe3
HfTe3 single crystal undergoes a charge-density-wave (CDW) transition at TCDW = 93 K without the appearance of superconductivity (SC) down to 50 mK at ambient pressure. Here, we determined its CDW vector q = 0.91...

Open AccessSurvival of itinerant excitations and quantum spin state transitions in YbMgGaO4 with chemical disorder
A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question is whether the QSL survives disorder or the disor...

ZrC formation and the phase relations in the Si–Zr–Mg–O–C system
When MgO+ZrO2 were used as a sintering aid to SiC ceramics, it was found that ZrO2 reacted with SiC and MgO to form ZrC and a magnesium silicate. This reaction may provide a new route to synthesize ZrC or prepare...
