    Abstract: A cancellation effect is obtained between the temperaturedependent phenomenon of the externally applied magnetic field and the crystallographic orientation of a gyromagnetic element by utilizing a temperature compensating magnetic shunt in combination with a permanent magnet used to establish a unidirectional or DC magnetic field through the gyromagnetic element comprising a YIG sphere and selectively orienting its axis to a predetermined angle defined by the direction of the DC magnetic field wherein the resonance frequency of the YIG sphere increases with temperature. Thus, any decrease in saturation magnetization as a function of temperature is exactly cancelled out by selective orientation of the YIG sphere.

    Abstract translation: 通过利用温度补偿磁分流与用于通过回旋磁场建立单向或直流磁场的永磁体结合,外部施加的磁场的温度依赖性现象与回旋磁性元件的结晶取向之间获得消除效果 元件,其包括YIG球并且选择性地将其轴定向到由DC磁场的方向限定的预定角度,其中YIG球体的谐振频率随着温度而增加。 因此,作为温度的函数的饱和磁化强度的任何降低通过YIG球的选择性取向被精确抵消。
