Title
High-temperature superconductivity is closely adjacent to a long-range antiferromagnet, which is called a parent compound. In cuprates, all parent compounds are alike and carrier doping leads to superconductivity, so a unified phase diagram can be dr...
Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy ...
We have systematically studied the nematic susceptibility in non-superconducting Ba(Fe$_{1-x}$TM$_{x}$)$_2$As$_2$ (TM = Cr, Mn, V and Cu) by measuring the uniaxial pressure dependence of the resistivity along the Fe-As-Fe direction. The nematic susce...
We have systematically studied physical properties of BaðFe0.97Cr0.03Þ2ðAs1−xPxÞ2, where super-conductivity in BaFe2ðAs1−xPxÞ2is fully suppressed by just 3% of Cr substitution of Fe. A quantum criticalpoint is revealed atx∼0.42, where non-Fermi-liqui...
