Brebis Bleaney

from Wikipedia, the free encyclopedia

Brebis Bleaney (born June 6, 1915 in London , † November 4, 2006 in Oxford ) was a British physicist who dealt with experimental solid-state physics.

Bleaney had an English father and a Danish mother. He attended on a scholarship to Westminster City School and studied from 1934 at St. John's College of Oxford University , where he graduated in 1937 with honors and in 1939 Francis Simon received his doctorate. During World War II he worked on the development of klystrons for radar. After the Second World War, he applied the techniques he had learned to physics, especially when studying the magnetic properties of solids. He developed the electron spin resonance method (ESR), which was introduced independently in 1944 in the Soviet Union ( Evgeni Konstantinowitsch Sawoiski ), but Bleaney was not aware of this.

The first experiments showed a broad attenuation due to the interaction of the electrons with the crystal (which could be controlled by transition to low temperatures) and the interaction of the magnetic moments of the electrons with each other, which could be suppressed by "dilution" with non-magnetic ions. The first experiments with Roger Penrose and Betty Plumpton (the later wife of Bleaney) showed the hyperfine structure interaction of the magnetic moments of the electrons with those of the nuclei.

He then applied the ESR technique to a variety of materials and collaborated with theorists from Maurice Pryce's group, in particular Anatole Abragam , in the interpretation of the experiments .

From 1957 to 1977 he headed the Clarendon Laboratory . Since he wanted to devote himself more to research and less administrative tasks, he gave up management in 1977. In 1978 he was elected to the American Academy of Arts and Sciences .

In 1984 he received the Holweck Prize . He was a Fellow of the Royal Society (1950) and a corresponding member of the Académie des sciences (1974). In 1964 he became CBE .

He was married to the physicist Betty Plumpton and had two children.
