abstract = {The authors determine from first principles the Curie
temperature T-C for bulk Co in the hcp, fcc, bcc, and
body-centered-tetragonal (bct) phases, for FeCo alloys, and
for bcc and bct Fe. For bcc Co, T-C=1420 K is predicted.
This would be the highest Curie temperature among the Co
phases, suggesting that bcc-Co/MgO/bcc-Co tunnel junctions
offer high magnetoresistance ratios even at room
temperature. The Curie temperatures are calculated by
mapping ab initio results to a Heisenberg model, which is
solved by a Monte Carlo method. (c) 2007 American Institute
