«In contrast, the highly crystalline and uniformly flat 2 - D CGT, together
with its small intrinsic anisotropy, allows small
external magnetic fields to effectively engineer the anisotropy, enabling an unprecedented
magnetic field control of ferromagnetic transition temperatures.»
External magnetic fields exert forces on them, levitate them against gravity and keep them together; the atoms are trapped in a
magnetic cage
with invisible walls formed by
magnetic fields.
For targeted non-invasive medicine delivery, these nano - swimmers could be coated
with medicine, injected into the bloodstream and roughly steered by
external magnetic fields.
The capsule is used
with a fixed
external magnet and its position is tracked precisely by measuring the strength and direction of the
magnetic field it experiences.
There are two main theoretical models, one based on small magnetite particles that may reorient in an
external magnetic field and the other based on the idea that upon photo excitation a certain type of molecules in the eye of a bird support a radical pair formed by two electrons which evolve under the joint action of the Zeeman interaction
with the
external magnetic field and the hyperfine interaction
with the supporting molecule.
Together
with adiabatic rotations of the
external magnetic fields or rotations of the nanodiamonds leads to over 10,000-fold enhancement in the 13C polarization.
Another apparatus associated
with this invention includes a receiver resonator including at least two loop resonators capable of resonating in the presence of an
external non-radiative
magnetic field, the at least two loop resonators being disposed in such that the
magnetic field received by each is substantially orthogonal to that received by the other.
