Evaluation of SrGaxInyFe12−(x+y)O19 single crystals

Investigation of structural, magnetic and dielectric properties of gallium substituted Z-type Sr3Co2-Ga Fe24O41 hexaferrites for microwave absorbers

“…Strontium hexagallate (SrGa 12 O 19 ) exists as an analogue of SrFe 12 O 19 (SrM) ferrite [35], and has been used as a substrate for epitaxial crystal growth of M-type hexaferrites. Single crystals of gallium substituted BaM [36,37], PbM [38] and SrM [39] were studied at GHz frequencies in the 1980's and 1990's, and polycrystalline PbFe 12ex Ga x O 19 was reported in 2002 [40]. Since then there have been many studies on polycrystalline gallium substituted M-type hexaferrites, such as the work by Trukhanov et al On Ga substituted BaM [41e48], as well as work by others on gallium mono-and co-substituted M-type hexaferrite [49e54].…”
