Superconductivity tests replicated
NZPA-AP New York Scientists in two laboratories said they had confirmed a report from researchers that a new kind of superconducting material loses all resistance to electricity at a record high temperature.
Researchers at the University of Arkansas said the material showed zero
resistance about —269 deg. Fahrenheit, more than 20deg. above previous widely accepted reports for stable superconducting compounds. Paul Chu, of the University of Houston, said he had confirmed the:' Arkansas results, finding zero resistance at —272 deg. He said his sample also
expelled an applied magnetic field, a hallmark of superconductivity called the Meissner effect. The results also have been confirmed by IBM researchers, according to a company spokesman,Jerry Present. Superconductivity is the ability to carry current without resistance.
