Magnetic garnet layers with the composition of (LuNdBi)3(FeAl)5O12 have been grown on (111)-oriented Gd3Ga5O12 (GGG) substrates, which are patterned with stripes of different widths using a Ti mask, by liquid-phase epitaxy to fabricate one-step grown magnetic garnet waveguides. The garnet layers were investigated by scanning electron microscopy, X-ray diffraction measurements, energy-dispersive X-ray analysis and reflection high-energy electron diffraction. The layers grown on Ti-masked regions had a coarse and uneven surface, which is attributed to the damage in the surface of GGG substrates during the growth. The waveguiding experiment indicated that the light waves could be guided within the waveguide with a propagation loss of approximately 0.7 dB/mm.
