From Scientific American:
``The 3He Superfluids," by O. Lounasmaa and G. Pickett, June 1990, page 104.
``Superfluid Turbulence," by R. Donnelly, November 1988, page 100.
``Quantum Dots," by M. Reed, January 1993, page 118.
From Physics Today (usually a bit harder than Scientific American):
``The Discovery of Superconductivity," by J. Denobel and P. Lindenfeld, Volume 49 Number 9, page 40 (1996). This one is short, primarily history rather than science, and very readable.
``Superconducting Magnets above 20 Tesla,'' by S. van Sciver and K. Marken, Volume 55 Number 8, page 37 (2002).
``Electrosensory Organisms," by J. Bastian, Volume 47 Number 2, page 30 (1994).
``The Physics of Granular Materials," by H. Jaeger, S. Nagel, and R. Behringer, Volume 49 Number 4, page 32 (1996).
