Abstract: In the present paper we show that a fine paramagnetic peculiarity discovered recently in superconductors, and another weakly expressed effect noticed just before the well-known specific-heat jump (detected half a century ago by Corak and Satterthwaite, but passed unnoticed so far) have the same physical origin. To explain these effects and indicate the reason of their common origin we used an advanced conception, which admits the existence of two types of Cooper pairs in superconductive ($SC$) materials – singlet and triplet. According to our understanding, they show radically different, non-traditional temperature behaviour appon cooling of $SC$ material, disscused in details in the present paper.
