Electromagnetically induced transparency allows for controllable change ofabsorption properties which can be exploited in a number of applicationsincluding optical quantum memory. In this paper, we present a study of theelectromagnetically induced transparency in $^{167}$Er:$^6$LiYF$_4$ crystal atlow magnetic fields and ultra-low temperatures. Experimental measurement schemeemploys optical vector network analysis which provides high precisionmeasurement of amplitude, phase and pulse delay. We found that sub-Kelvintemperatures are the necessary requirement for studying electromagneticallyinduced transparency in this crystal at low fields. A good agreement betweentheory and experiment is achieved taking into account the phonon bottleneckeffect.
