Edwards S F & Anderson P W. Theory of spin glasses. J. Phys.—F—MetaI Phys. 5:965-74, 1975

When magnetic atoms are dispersed in a nonmagnetic metallic matrix, the forces between their magnetic moments depend on separation and are sometimes of ferromagnetic type and sometimes antiferromagnetic. The net experimental observation is thermodynamic, not magnetic, and shows a phase change at low temperatures. Both phases are nonmagnetic and apparently completely disordered. This paper inven...

Major F. W. Cragg

It is with the deepest regret that we learn of the tragic death of Major F. W. Cragg, i.m.s., from typhus fever at Lahore on the 23rd of April, 1924. Major Cragg's death adds another name to the long but brilliant list of scientific investigators who have lost their lives in the prosecution of medical enquiries for the benefit of humanity. He died as truly on active service as did any officer k...

F/W e+e- INTERACTIONS*

INTRODUCTION The field of e+e-interactions has provided a great deal of excitement in the past few years. 1-9 Primarily, interest has centered around the reaction +-ee-hadrons. This reaction is particularly attractive because we believe in electromagnetic perturbation theory, which implies that the cross section for hadron production is dominated by one photon annihilation of the electron and p...
