Magnetic device and method of manufacture. |
摘要 |
This invention concerns with devices comprising a body of magnetic material and methods of their manufacturing. Crystals or neodymium and praseodymium iron garnet materials have Faraday rotation which render such materials suitable for use, in magnetic and, especially magneto-optic devices such as e.g., as antireciprocal components e.g. optical isolators, in optical devices and communications systems. These materials can be made by liquid-phase epitaxy on a substrate having suitable lattice parameters, deposition being carried out at relatively low melt temperatures. |
