Phys. Rev. B 66, 144407 (2002) [6 pages]Model of localized highly frustrated ferromagnetism: The kagomé spin iceReceived 26 July 2001; revised 9 August 2002; published 14 October 2002 A model of localized highly frustrated ferromagnetism is presented: kagomé spin ice. Using analytical and Monte Carlo calculations its massive ground-state entropy is evaluated. Monte Carlo calculations are also used to explore the phases in the presence of further-neighbor interactions and applied fields. The importance of thermal spin fluctuations and their ability to stabilize a variety of magnetic structures is clearly manifested. Remarkably, some of these phases are only partially ordered and present both disordered and ordered sublattices. © 2002 The American Physical Society URL:
