  We report the development of a CaMoO4 crystal low temperature detector for
the AMoRE neutrinoless double beta decay (0{\nu}\b{eta}\b{eta}) search
experiment. The prototype detector cell was composed of a 216 g CaMoO4 crystal
and a metallic magnetic calorimeter. An over-ground measurement demonstrated
FWHM resolution of 6-11 keV for full absorption gamma peaks. Pulse shape
discrimination was clearly demonstrated in the phonon signals, and 7.6 {\sigma}
of discrimination power was found for the {\alpha} and \b{eta}/{\gamma}
separation. The phonon signals showed rise-times of about 1 ms. It is expected
that the relatively fast rise-time will increase the rejection efficiency of
two-neutrino double beta decay pile-up events which can be one of the major
background sources in 0{\nu}\b{eta}\b{eta} searches.
