Pierre Weiss

Pierre -Ernest Weiss ( German script sometimes white, born March 25, 1865 in Mulhouse, † October 24, 1940 in Lyon ) was an Alsatian physicist.

Biography

1887 joined Pierre -Ernest Weiss as valedictorian at the Zurich Polytechnic his engineering degree from. The following year he went to the École Normale Supérieure in Paris. In France, he began to deal with physics. In 1895 he went to the University of Rennes, 1899 at the Lyon and in 1902 he was appointed professor at the Polytechnic in Zurich. There he received a laboratory for the study of magnetic phenomena. In 1908 he was co-founder of the Swiss Physical Society. In 1919 he became head of the Physics Institute of the University of Strasbourg. In 1926 he was admitted to the Paris Academy.

Weiss laid the foundations of the para-and ferromagnetism, and the temperature dependence of the magnetization. He discovered the white between districts and the quantumful properties of the magnetic moments in the atoms. He also developed the Curie law of Pierre Curie on to mitbenannten after him Curie -Weiss law. With his friend Heike Kamerlingh Onnes he worked on magnetism at very low temperatures.

Works

His most important publication was the work of Le magnétisme in 1926.
