- •
We present fabrications and properties of the L-T and L-T mode ME composites.
- •
The equivalent magnetic noise levels at high frequency are measured.
- •
The equivalent magnetic noise of the L-W mode sensor is 0.78 pT/Hz1/2 at 30 kHz.
- •
The dominated noise source can be confirmed from OPA at high frequency range.
