| Abstract: |
We summarize recent results at NIST to develop high-performance yet highly miniaturized magnetic sensors based on atomic vapors confined in microfabricated alkali vapor cells. These sensors currently achieve sensitivities in the range of a few tens of femtotesla in a 1 Hz bandwidth in detection volumes of about 1 mm3. The require no cooling and only a small amount of heating, making them ideal for deployment in remote, power starved locations. The low potential cost of arrays of these sensors. |
