Description:
The concept of quantum criticality is proving to be central to attempts to understand the physics of strongly correlated electrons. Here, we argue that observations on the itinerant metamagnet Sr3Ru2O7 represent good evidence for a new class of quantum critical point, arising when the critical end point terminating a line of first-order transitions is depressed toward zero temperature. This is of interest both in its own right and because of the convenience of having a quantum critical point for which the tuning parameter is the magnetic field. The relationship between the resultant critical fluctuations and novel behavior very near the critical field is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grigera, S A -- Perry, R S -- Schofield, A J -- Chiao, M -- Julian, S R -- Lonzarich, G G -- Ikeda, S I -- Maeno, Y -- Millis, A J -- Mackenzie, A P -- New York, N.Y. -- Science. 2001 Oct 12;294(5541):329-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Physics and Astronomy, University of St. Andrews, North Haugh, St. Andrews, Fife KY16 9SS, UK. s.grigera@bham.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11598292" target="_blank"〉PubMed〈/a〉
