Abstract

s relation, the zero-temperature value of the London penetration depth lambda(0) is related to the specific heat jump Delta C and the slope of upper critical field dH(c2)/dT at the transition temperature T-c, provided the data on Delta lambda = lambda(T) - lambda(0) are available in a broad temperature domain. We then provide a way to determine lambda(0), the quantity difficult to determine within many techniques.
