QM to Host Workshop on Iron Pnictide Superconductors

QM held a mini-workshop on January 29th in Cambridge on the family of Iron Pnictide superconductors. The primary focus was to showcase the power of diverse techniques utilised in the creation, characterisation, and measurement of materials belonging to this exciting category of new high temperature superconductors. With the focus on various capabilities that can be used to study new materials, speakers were asked to broadly introduce their technique to a general audience, followed by an example of results yielded on the family of Iron Arsenide compounds. The local organizing committee consisted of Jack Gillett, Suchitra Sebastian, Mike Sutherland and Gil Lonzarich.

QM Paper in Nature reveals breakdown of Fermi Liquid physics

QM group members have published a paper in the Oct. 30 journal of Nature which provides a detailed picture of how the standard metallic state breaks down in the presence of soft magnetic fluctuations. The study, which involved measurements of charge and thermal transport in ZrZn2 involved Rob Smith, Michael Sutherland, Montu Saxena and Gil Lonzarich. A news and views article on the work places the results in context (access to Nature website required).

Workshop on Critical Fluctuations

Prof. David Khmelnitskii will give a seminar on Wednesday, Oct. 07 celebrating Prof. Pippard's accomplishments.

Emeritus QM group member John Waldram has written a comprehensive obituary of Brian, which can be found on the university website.

Another detailed obituary written by Richard Eden, a Fellow of Clare Hall, can be found on the department's webpage. The Guardian newspaper also has an account of his life and work.

QM team publishes breakthrough paper in Nature

QM's Suchitra Sebastian and Gil Lonzarich recently published research on a class of materials known as 'high temperature superconductors' in the influential journal Nature. The work describes the behaviour of electrons in very pure samples of YBa2Cu3O6.51 in the world's highest magnetic fields, where they uncover evidence which might help understand the relationship between supercondutivity and magnetism. Press coverage of the study include a release from the National High Magnetic Field Laboratory where the study was performed, and an article on Science Daily .
