ferromagnetic

(fer″ō-mag-net′ik) [ ferro- + magnetic]

Pert. to a metal (e.g., cobalt, iron, nickel, and some alloys) capable of being magnetized when placed in a magnetic field.

CAUTION!

Ferromagnetic materials are unsafe in magnetic resonance imaging environments.

Occurrence of ferromagnetism at the room temperature (RTFM) in ZnO is connected to the presence of oxygen vacancies (VO) [4, 5], vacancies of Zn (V[Z.sub.n]) [6, 7], and interstitial atoms Zn ([Zn.sub.i]) [8].

Structural and Magnetic Properties of Nanopowders and Coatings of Carbon-Doped Zinc Oxide Prepared by Pulsed Electron Beam Evaporation

Comparatively with undoped ZnO film, all Ni-doped ZnO films show distinctly hysteresis loops, indicating that samples have room-temperature ferromagnetism. The magnetic moments increase with the content of Ni ions from [M.sub.s] = 5 x [10.sup.-7] A[m.sup.2] (for x = 0.03), [M.sub.s] = 2.4 x [10.sup.-6] A[m.sup.2] (for x = 0.05), and [M.sub.s] = 6 x [10.sup.-6] A[m.sup.2] (for x = 0.1).

The influence of doping with transition metal ions on the structure and magnetic properties of zinc oxide thin films

In accordance with the TEM technique, all synthesized samples have unlike domains of nanoparticle sizes and those for x = 0.02 and 0.06 [less than or equal to] x [less than or equal to] 0.10, possess number of particles with sizes smaller than 35 nm that might explain the emergence of superparamagnetism and accordingly smaller contribution to ferromagnetism.

Structural, Morphological, Optical, and Room Temperature Magnetic Characterization on Pure and Sm-Doped ZnO Nanoparticles

The photoinduced ferromagnetism is strongly affected by the photon energy itself rather than the intensity of the corresponding photon absorption.

Phototunable magnetism in copper octacyanomolybdate

We can see a similiar magnetic domain structure in the theoretical model of ferromagnetism. In the case of Fig.2, the domain shape and the dipole direction tend to depend on the crystal structure.

Pedagogic demonstration of spontaneously broken symmetry by magnetic compasses

This alignment, called ferromagnetic coupling, rarely occurs naturally because electrons tend to spin in opposite directions, cancelling out any potential ferromagnetism. But PMPOT-18's structure apparently encourages the necessary coupling.

Progress in designing magnetic polymers

There is even more variety in the electronic properties of various carbon allotropes, which range from superconductivity to ferromagnetism and tunable electrical conductivity [1].
