“…6,7 Measurements on CeRu 2 have supported the prediction that supercooling by reducing H reduces the effective free energy barrier seen by the metastable state, and supercooling is best achieved by reducing T in constant H, i.e., by field cooling. Signatures of supercooling across a FOT in vortex matter have also been reported in various other superconductors such as YBCO, 8,9 NbSe 2 , 10 BSCCO, 11 Nb, 12 V 3 Si, 13,14 etc. Measurements on V 3 Si ͑Ref.…”
