Abstract:The initial depression of the superconducting temperature of (La, Th) Ce alloys has been measured. It has been found that there is a steep maximum in the initial depression as a function of La concentration in the (La, Th) matrix, This effect is compared with the nonmonotonic behaviour of the critical temperature of LaCe under pressure.
