Spectral hole burning technique is well-deployed in optical inhomogeneously broaden medium for realization of slow light and optical memory based on atomic frequency combs. First implementation of this technique into the microwave regime has been recently demonstrated with NV-centers coupled to a cavity [1]. Here, we develop this idea by applying spectral hole burning technique to Erbium spin ensemble in a cavity-free regime. We investigate Erbium-doped Y2SiO5 crystal coupled to a superconducting transmission line. Here, we show the influence of the magnetic field and temperature on the dynamics of the attained spectral hole and discuss processes governing it.
