Description

Synthetic crystalline garnets doped with the rare-earth elements are commonly used as a host materials in acoustic transmitters and numerous nonlinear optics applications because of their ability to generate ultra short pulses. 57Fe emission Mössbauer spectroscopy (eMS) following implantation of 57Mn (T½ = 1.5 min.) in the temperature range from 298 K to 798 K has been applied to study the lattice location and properties of Fe in three types of single crystal garnet structures: yttrium iron garnet Y3Fe5O12 (YIG), gadolinium gallium garnet Gd3Ga5O12 (GGG) and yttrium aluminium garnet (YAG, Y3Al5O12). The results show that introducing point defects by ion implantation is a possible method of tailoring magnetic properties in the ferromagnetic garnet system.
