The local magnetic field in the bulk of superconducting single crystal ␤ tin was measured near and across the transition between the normal ͑N͒ and intermediate ͑I͒ state at Tϭ0.08 K. With varying applied field H a , the data indicate a reversible phase transition within the I state at H t Ϸ295 Oe, interpreted as a transition from the laminar to a tubular structure. Near the I→N transition, occurring at H cI ϭ0.98H c0 ϭ300 Oe, the field B in the N domains is strongly inhomogeneous with B ϽH c0 , it grows with the decrease of H a towards the value H c0 ϭ305.5Ϯ0.5 Oe. On lowering H a in the N state, a large ''field supercooling'' (␦H/H c Ϸ6%) of this state was observed.

“…The results of this calculation are shown in Figure 41, together with the data of Gurevich (98). The parameters of the theory for this fit are Ea = 75.2 X 10-3 eV and J = 18.4 X 10-6 eV.…”

“…The time dependence of the depolarization .. can be used to study the diffusion of f.1 +. Figure 38 shows a summary of data on the temperature dependence of the depolarization rate (98,104). One can easily show that the expression for the motional narrowing (Equation 29) simplifies for the case where (t/:r) is large or small.…”

~1.0 Volume fraction (CH 3 0H in benzene) Volume fraction (CHCl 3 1n CH 3 0H) Figure 7 (left) Measured asymmetry of Jl + precession and corresponding residual polarization P"' as a function of the volume fraction of CH 3 0H in Ct5H 6 in two transverse magnetic fields. Circles represent data from LBL at 100 G; triangles represent data from JINR at 50 G. The dotted line indicates how the asymmetry would be expected to change if benzene gave "sponge-like" protection to CH 3 0H. (right) Similar data from LBL on CH 3 0H/CHC1 4 mixtures in 100 G fields. The dotted line here indicates how the asymmetry is expected .to vary if selective reaction by CHCI 3 were possible, or if spur scavenging by CHCI 3 occurred.
