Francis Bitter

from Wikipedia, the free encyclopedia

Francis Bitter (born July 22, 1902 in Weehawken Township , New Jersey , † July 26, 1967 ) was an American physicist .

Bitter began his studies at the University of Chicago in 1919 and graduated from Columbia University in 1925 . He then continued his studies in Berlin in 1925/26 and received his Ph.D. from Columbia University in 1928. PhD.

Later, Bitter was primarily a professor of physics at the Massachusetts Institute of Technology (MIT). In 1950 he was elected to the American Academy of Arts and Sciences . Since 1931 he was a fellow of the American Physical Society .

He delivered significant work on ferromagnetism and the development of powerful electromagnets - namely the bitter magnets developed in the 1930s at the Department of Mining and Metallurgy at MIT and named after him.

The bitter stripes are also named after him. These give clear evidence of the existence of the Weiss districts . Sometimes the patterns resulting from the distribution of fine ferromagnetic powder on a magnet (images of the Weiss districts) are also named after Nikolai Sergejewitsch Akulow (Akulow-Bitter pattern). Both found this around 1931.
