【摘要】 本文导出了更精确的单晶铁磁共振公式,其近似度达到磁晶各向异性场的平方项。在此基础上,讨论了由磁晶各向异性场引起的YIG(钇铁石榴石)单晶微波器件的温度不稳定性的补偿问题,对以往引用的温度补偿方向作了较大修正,并给出了外磁场沿修正的补偿方向时计算YIG器件温度特性的具体公式。更多还原

【Abstract】 More precise analytic expressions for ferromagnetic resonance of single crystals are calculated, the approximation being carried to terms quadratic in the magneto-crystalline anisotropy field. On the basis of these, the problem of the compensation of the temperature instabilities of single crystal YIG microwave devices, caused by the variations of the anisotropy field, is discussed. Significant corrections to the temperature compensation directions that have been in use are introduced. Formulae for the calculation of the temperature characteristics of YIG devices with the applied magnetic field in the corrected compensation directions are given.更多还原
