      abstract     = {Electromagnetically induced transparency allows for the
                      controllable change of absorption properties, which can be
                      exploited in a number of applications including optical
                      quantum memory. In this paper, we present a study of the
                      electromagnetically induced transparency in a 167Er:7LiYF4
                      crystal at low magnetic fields and ultra-low temperatures.
                      The experimental measurement scheme employs an optical
                      vector network analysis that provides high precision
                      measurement of amplitude, phase and group delay and paves
                      the way towards full on-chip integration of optical quantum
                      memory setups. We found that sub-Kelvin temperatures are the
                      necessary requirement for observing electromagnetically
                      induced transparency in this crystal at low fields. A good
                      agreement between theory and experiment is achieved by
                      taking into account the phonon bottleneck effect.},
