We demonstrate the feasibility of a read head using a high-resistance spin-dependent tunneling (SDT) junction. The head consists of a 1.5 /spl mu/m or 1.7 /spl mu/m wide flux guide on top of the junction. The junction is about 0.8 /spl mu/m wide and

Melt refining experiments in which irradiated uranium or synthetic EBR- II alloys were melted in oxide crucibles showed that removal of zirconium as an oxide does not occur at temperatares up to 1400 ts C. Removal of zirconium by carbon scavenging of

Melt refining of synthetic EBR-II alloy in stabilized zirconia crucibles at 1400 ts C for 3 hr under one atmosphere of helium pressure resulted in almost complete volatilization of iodine from ingot and skull fractions. Removal of iodine was strongly

Sessile drops of liquid uranium on five refractory oxide substrates were studied photographically. The volume expansion on melting ( approximately 3%), the contact angles (135 plus or minus 3 deg in each case), and the surface tension of the liquid (
