Zener, Clarence

The Snoek pendulum, which in the most general sense is a device to measure relaxations, has also been used to measure relaxation caused by tangential displacements at grain boundaries. This application has been the central concern of a distinguished Chinese physicist, Tingsui Ke, for all of the past 55 years. He was stimulated to this study by Clarence Zener, in 1945, and pursued the approach, first in Chicago and then in China. This exceptional fidelity to a powerful quantitative technique was recognised by a medal and an invitation to deliver an overview lecture in America, recently published shortly before his death (Ke 1999). 

Schweber and others have argued that quantum chemistry was a quintessentially American discipline, with Mulliken, Slater, Van Vleck, Urey, Pauling, Edward Condon, Oppenheimer, Ralph Kronig, I. I. Rabi, Clarence Zener, David Dennison, Philip M. Morse, Eyring, John G. Kirkwood, George E. 

Zener, C (1951) Interaction between the d-shells in the transition metals, Phys. Rev. 81,440 and Interaction between the d-shells in the transition metals 2 Ferromagnetic compounds of manganese with perovskite structure, Phys. Rev. 82, 403. These two papers have been cited collectively almost 4000 times and describe the double exchange mechanism. Clarence Zener spent a short time (1940-1942) as an instructor at Washington State University when it was still known as Washington State College.
