The interaction of charge carriers
with magnetic moments is of critical importance but remains a challenge to understand..
Not exact matches
EPR, by contrast, detects the
magnetic moment associated
with unpaired conduction electrons in metallic lithium
with very high sensitivity and time resolution on the order of a few minutes or even seconds.
Bismuth ferrite is an antiferromagnetic, which means that the
magnetic moments of its
magnetic sublattices (structures formed by atoms
with the same parallel spins) cancel each other out, and the total magnetization of the material is close to zero.
The work relies on a model system called a Kondo chain, where flowing electrons interact
with local
magnetic moments within a material.
Although there were
moments when the planet's
magnetic shields held firm, it spent far more time
with weak shields than strong shields.
A unique property of the molecule is the large permanent dipole
moment, which reacts
with an electric field much like a bar magnet reacts
with a
magnetic field.
Researchers have recently been also interested in the utilization of antiferromagnets, which are materials without macroscopic magnetization but
with a staggered orientation of their microscopic
magnetic moments.
QSLs are strange states achieved in solid materials where the
magnetic moments, or «spins,» associated
with electrons exhibit a fluidlike behavior.

with a pronounced
magnetic moment, a spin, is located.
Each electron has a
magnetic direction which is slightly distorted
with respect to the adjoining electron — therefore the electrons create spiral of
magnetic moments.
This large anisotropy leads to a remarkable
magnetic moment, which has been determined
with synchrotron - based measurements at the X-Treme beamline at the Swiss Light Source.

magnetic fields, they get into resonance
with radio waves or microwaves, which changes the
magnetic moment in such a way that the atoms fly away and escape from the trap.
Moreover, these
magnetic moments interact strongly
with the electrons in graphene which carry electrical currents, giving rise to a significant extra electrical resistance at low temperature, known as the Kondo effect.
Although utilized for rock
magnetic applications as well, through software and procedures developed
with collaborators at MIT and Harvard, the
magnetic moment can be calculated from very weak
magnetic samples to address paleomagnetic questions.
To better understand the complex influence of the electron shell on measurements of nuclear
magnetic moments, scientists at TU Darmstadt now want to conduct measurements of nuclear
magnetic moments on atomic nuclei
with just a single bound electron or no electron shell at all.
The neutron's
magnetic moment can also interact
with magnetic spins in a material.
If you think a Fodi would fold itself easily into your life, you can get one through Kickstarter at the
moment, where it costs just $ 14 and comes
with a clever
magnetic cable holder to keep charging cables neat and tidy.
