  We have used images obtained with the Infrared Array Camera and the Multiband
Imaging Photometer onboard the Spitzer Space Telescope to search for low-mass
stars and brown dwarfs with circumstellar disks in the Chamaeleon I
star-forming region. Through optical spectroscopy of sources with red colors in
these data, we have identified seven new disk-bearing members of the cluster.
Three of these objects are probably brown dwarfs according to their spectral
types (M8, M8.5, M8-L0). Three of the other new members may have edge-on disks
based on the shapes of their infrared spectral energy distributions. One of the
possible edge-on systems has a steeply rising slope from 4.5 to 24um,
indicating that it could be a class I source (star+disk+envelope) rather than a
class II source (star+disk). If so, then it would be one of the least massive
known class I protostars (M5.75, M~0.1 Msun).
