Felix (1905-1983) was born in Zurich, Switzerland. He received his Ph.D. in 1928 from the University of Leipzig where he worked with Heisenberg. Upon Hitler s rise to power Bloch left Europe and moved to the United States where he accepted a position at Stanford University. He was awarded the 1952 Nobel Prize in Physics for the development of the NMR technique. 

Josephson, Brian David (1940- ) was bom in Cardiff, Wales and discovered the Josephson effect while a 22-year-old graduate student at the University of Cambridge. He won the Nobel Prize in physics in 1973 for his discovery. 

Lenz (pronounced lents), Heinrich Friedrich Emil (1804—1865) was bom in Dorpat, Russian Empire (now Tartu, Estonia) and formulated his eponymous law of electromagnetism in 1833. He participated in a round-the-world expedition in 1823-1826 and made extremely accurate measurements of the properties of seawater. 

London, Fritz (1900-1954) was bom in Breslau, Germany (now Wroclaw, Poland). He fled Nazi Germany in 1933 and came to the United States in 1939 where he became naturalized in 1945. Together with his younger brother Heinz he formulated the London equations of superconductivity.

Mossbauer spectroscopy has been extensively used for studies of nanostructured materials and several reviews on magnetic nanoparticles have been published, see e.g. [6-8, 46 8]. The magnetic properties of nanoparticles may differ from those of bulk materials for several reasons. The most dramatic effect of a small particle size is that the magnetization direction is not stable at finite temperatures, but fluctuates. 

Numerous experimental studies have shown that the magnetic hyperfine field of magnetic nanoparticles varies linearly with temperature at low temperatures, in accordance with (6.23). This is in contrast to bulk materials for which the decrease in the hyperfine field with increasing temperature in accordance with spin wave...
