We probe the energy landscape of the 3D Edwards-Anderson spin glass in a ma
gnetic field to test for a spin glass ordering, We find that the spin glass
susceptibility is anomalously large on the lattice sizes we can reach. Our
data suggest that a transition from the spin glass to the paramagnetic pha
se takes place at B-c approximate to 0.65, though the possibility B-c = 0 c
annot be excluded. We also discuss the question of the nature of the putati
ve frozen phase.
