We report static magnetic susceptibility data, g(T), for the a and P phases ef the organic conductor di[bis(ethylenediothiolo)tetrathiafulvalene] tri-iodide [(BEDT-TTF)zlz] both at ambient pressure and under applied pressures of up to 10 kbar. Ambient pressure ESR data for both phases belo3 00 K are also presented. The temperature dependence of the spin susceptibility g~(T) for the superconductor P-(BEDT-i i'F)zlz is unusually small for organic conductors; the pressure derivative 81~~/3P is found to be only moderate in magnitude ( -3.3' per kbar) and independent of temperature beloved 300 K. For the a phase, Bing, /BP= -2.0%/kbar at ambient temperature.

Bi-Sr-Ca-Cu-O superconducting phases are found to be extremely sensitive to furnace atmosphere. Experiments have been conducted in still air and flowing air, oxygen, nitrogen and argon. Air atmosphere is found best suited for the high-Tc phase. Two A-face centred tetragonal phases, one with a=5.3855 AA, c=24.463 AA, c/a=4.542 and the other with a=5.380 AA, c=30.702 AA, c/a=5.707, are recognised in the samples depending upon the composition and heat treatment.
