Abstract
We have calculated the temperature-dependent London penetration depth in a recently proposed phenomenological, marginal-Fermi-liquid model that has been shown to be quite successful in explaining several of the observed anomalous properties of the normal state. Solutions with temperature dependence close to the two-fluid model and to experiment can be found. However, they do not correspond to a value of twice the gap to critical temperature as large as the recently suggested value of 8 for Y-Ba-Cu-O.Keywords
