Publication of their results advanced Mller’s reputation, leading to his promotion in 1970 to titular professor at the University of Zurich and, in 1972, to his becoming head of the IBM laboratory’s physics group. As a physics student, Mller had learned of the 1911 discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes. Having developed techniques for achieving extremely low temperatures, Kamerlingh Onnes was able to liquefy helium, and he found that, at liquid helium temperatures, such metals as mercury exhibited a total loss of electrical resistance. Since Kamerlingh Onnes’s work, scientists had found other metals and alloys that superconducted, including an alloy of tin and germanium that superconducted at 23.2 kelvins. In the early 1970’s, Mller, stimulated by certain calculations on metallic hydrogen, investigated the possibility of incorporating hydrogen into a perovskite to create a metallic state that might superconduct, but his calculations led him to conclude that the required density of hydrogen within the structure was unattainable. 12 Darling Dad Tattoo Designs 2016.
