Sentences with phrase «detection of magnetic fields»

The detection of magnetic fields is carried out with the help of a so called nitrogen vacancy center (NV), located approximately 10 nanometers below the surface of the diamond tip.

Not exact matches

Diamonds designed with nitrogen - vacancy (NV) centers that can detect changes in magnetic fields are a powerful tool for biosensing technologies and used in the medical detection and diagnosis of disease.

Phosphorus doping pushed over 90 percent of NV centers to the negative charge state, enabling magnetic field detection.

As a step toward that goal, the NIST researchers demonstrated detection of digitally modulated magnetic signals, that is, messages consisting of digital bits 0 and 1, by a magnetic - field sensor that relies on the quantum properties of rubidium atoms.

New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source's environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.

Similarly, changes in the ambient magnetic field are created by submarines passing below the surface of the ocean, and the U.S. Navy is very interested in SQUIDs for submarine detection.

In a study published in Physics Review Letters, and highlighted by APS Physics, ICFO researchers demonstrate a new technique for the coherent the detection of radio frequency magnetic fields using an atomic magnetometer.

The systematic lack of magnetic field detection reported in recent spectro - polarimetric surveys of Be stars is consistent with the absence of strong magnetic wind braking in these fast spinning stars but put strong constraints on the possible origin of the magnetic field.
