This paper has been temporarily withdrawn by the author because there are errors in it that require further study.

The MgB$_2$ superconductor, discovered in 2001, has provided unique compound features of magnesium diboride with much higher critical temperature and critical field compared to NbTi superconductor. Its applications have been expanding owing…

Magnesium diboride has many intriguing characteristics, including its relatively high critical temperature and two-band nature. Most prior studies of MgB2 thin film Josephson junctions have been conducted above 2 Kelvin. We report results…

Study and comparison of over 30 examples of electron doped BaFe2As2 for transition metal (TM) = Co, Ni, Cu, and (Co/Cu mixtures) have lead to an understanding that the suppression of the structural/antiferromagnetic phase transition to low…

Superconductivity commonly appears under pressure in charge density wave (CDW)-bearing transition metal dichalcogenides (TMDs), but has emerged so far only via either intercalation with electron donors or electrostatic doping in CDW-free…
