Brebis Bleaney

Brebis Bleaney ( born June 6, 1915 in London, † 4 November 2006) 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, the Westminster City School and studied from 1934 at St. John's College, Oxford University, where in 1937 he graduated with honors and received his doctorate at Simon Francis, 1939. During World War II he worked on the development of the klystron for radar. The techniques learned while he turned to after the Second World War in physics, especially in the study of magnetic properties of solids. He developed the electron spin resonance (ESR) method, which already in 1944 in the Soviet Union ( Yevgeny Konstantinovich Sawoiski ) was introduced independently what Bleaney was not known but.

The first experiments showed still a large attenuation by interaction of the electrons with the crystal (which could be controlled by the transition to low temperatures), and the interaction of the magnetic moments of the electrons with each other, which could be suppressed by 'dilution' with nonmagnetic ion. The first experiments with Roger Penrose and Betty Plumpton (later the wife of Bleaney ) showed 1949, the hyperfine interaction of the magnetic moments of the electrons with those of the nuclei.

He turned the ESR technique in a row on a variety of materials and worked in the interpretation of the experiments together with theorists from the group of Maurice Pryce, especially Anatole Abragam.

1957 to 1977 he headed the Clarendon Laboratory. Because he wanted to devote more research and less administrative duties, he gave the line in 1977.

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

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