C Glossary antiferromagnetism: In substances known as antiferromagnets, the magnetic moments of adjacent atoms tend to line up antiparallel, yielding an ordered state with no net magnetic moment. Consequently, such materials display almost no response to an external magnetic field at low temperatures.

critical field (Hc) : At zero applied current, the maximum magnetic field (at a given temperature)

cyclotron: Device for experimental particle physics that uses an oscillating electric field to accelerate charged particles and a magnetic field to control particle trajectories. Charged carriers of all kinds follow cyclotron-like spiral trajectories in magnetic fields.

: Method for precisely measuring the mass of a collection of ions originating from the chemical dissociation of complex molecules and solids; it depends on cyclotron resonance. Ions with a range of mass-to-charge ratios are exposed to a high-frequency electric field in the presence of a constant magnetic field perpendicular to the varying electric field.

National High Magnetic Field Laboratory (NHMFL) : National laboratory for the production of high and specialized magnetic fields for scientific research.

From page 143... ...
Only a finite number of different orientations are possible for the magnetic moments of any such nucleus in a magnetic field, each orientation having its own characteristic energy. This behavior

pulsed magnet: Resistive magnet designed to provide transient magnetic fields, often for durations as short as microseconds but occasionally for as long as several seconds. Because it is active for only short times, a pulsed magnet uses less power and needs less cooling than a DC magnet of similar bore and maximum field strength.

From page 145... ...
A magnet's energy is stored in its magnetic field. superconducting magnet: Electromagnet whose conductor is made of superconducting material.

This material may be derived from roughly machine-read images, and so is provided only to facilitate research.
