Magnetic test boosts case for record-setting superconductor

Meissner effect detected in relatively ‘warm’ hydrogen sulfide

8:30am, July 6, 2015

A promising material for conducting electrical current without resistance at a relatively high temperature has passed a crucial test. New magnetic measurements, detailed by German physicists in a study posted online June 26 at, indicate that pressurized hydrogen sulfide is a superconductor at roughly 200 kelvins.

The fresh data bolster the controversial claim of hydrogen sulfide superconductivity made by the same researchers in December (SN: 4/4/15, p. 11). If confirmed, the discovery would nudge physicists closer to their ultimate goal of room-temperature superconductivity (about 300 kelvins). No other known material is superconducting above 164 kelvins.
