Composite particles with magnetic properties, near

Oxygen sensing, magnetic, and upconversion luminescence properties are combined in multi-functional composite particles prepared herein by a simple mixing, baking, and grinding procedure.

This means the compound shows permanent magnetic properties rather than exhibiting them only in the presence of an external magnetic field (Figure (PageIndex{1})). In a ferromagnetic element, electrons of atoms are grouped into domains in which each domain has the same charge. In the presence of a magnetic field, these domains line up so that charges are parallel throughout the entire

Oxygen sensing, magnetic, and upconversion luminescence properties are combined in multi-functional composite particles prepared herein by a simple mixing, baking, and grinding procedure.

Finally, various magnetic properties of the particles have been studied as functions of field, temperature and size. Experimental procedure Materials Ferric chloride and cobalt chloride (98 +% purity) and sodium hydroxide were used. Oleic acid of HPCL grade was used as surfactant. All the materials were reagent grade and used without further purification. Double distilled, de-ionized water was

Maghemite particles are used as T 2 contrast agents for magnetic resonance imaging, especially for molecular and cellular imaging. Linear clusters of particles called nanoworms were recently developed to enhance the targeting efficiency. In this work, the magnetic and NMR relaxation properties of these nanoworms are studied at multiple magnetic fields. After the usual saturation at

New Syntheses of Cobalt Ferrite Particles in the Range 2−5

The size of cobalt ferrite particles from 2 to 5 nm is controlled by the reactant concentration in oil-in-water micelles. It is possible to obtain the particles either suspended in the solvent to form ferrofluid or in dry powder. When particles are isolated in a fluid, the interactions between particles are small. The magnetic size is similar to that determined by TEM. The reduced

The study of the magnetic properties of these samples included the measurement of both intrinsic (saturation magnetization) and extrinsic properties (coercive force and magnetization behavior in the approach to saturation region). It was found that all the above-mentioned quantities depended on the degree of order in the distribution of vacancies.

Magnetic properties of single domain ferromagnetic particles. Fine ferromagnetic particles occur in very many practical materials of scientific and technological importance. These include spin glasses, rocks, ferrofluids, magnetic recording tapes, permanent magnets, magnetotactic bacteria and other living organisms. It is hence beneficial to consider the magnetic properties of such particles
