Garnet ferrite for low-insertion-loss non-reciprocal circuit, method for preparing the same, and non-reciprocal circuit device including the same |
| 摘要 |
A garnet ferrite used for a non-reciprocal circuit device contains Fe in an amount lower than the value derived from stoichiometry by 0.5% to 5%, and more preferably by 1% to 3%. The garnet ferrite can exhibit a low insertion loss in a high-frequency band of more than 5 MHz.
