Latest Patents
Allen Sweet holds a patent for a "Single crystal YIG nanofilm fabricated by a metal organic decomposition epitaxial growth process." This MOD YIG epitaxial process allows for the fabrication of YIG nanofilms that exhibit single crystal epitaxial properties when deposited on GGG substrates. The films can have thicknesses of 50 nm for a single layer, 100 nm for two layers, and 130 nm for three layers. They possess a gyromagnetic ratio of 2.80 MHz per Oe, with Gilbert damping ranging from 0.0003 to 0.001. The 4πM values range between 1650 G to 1780 G, and coercivity varies from 1 Oe to 5 Oe. The surface roughness is measured at RMS 0.20 nm for up to 10 layers. This fabrication process is economical and utilizes a spinner, a drying station with temperature control from room temperature to 150°C, and a quartz tube furnace that accommodates a flowing atmosphere of research-grade oxygen, thus eliminating the need for high vacuum deposition chambers.
