Sentences with phrase «magnetic oxide material»

A magnetic oxide material incorporated into the nanoparticles could allow the assemblies to be directed to a tumor site by an external magnet, and could also support diagnostic imaging.

Not exact matches

The focus of this investigation is a hybrid material consisting of a thin nickel film on a vanadium oxide substrate; this hybrid material exhibits magnetic properties unlike any other magnetic material.

The hybrid between a simple magnetic material and a transition - metal oxide provides a «window» to understand the metal - to - insulator transition and offers dramatic tunability of magnetic properties.

But in crystals of an iron - molybdenum oxide, a team led by Kei - Ichiro Kobayashi at the Joint Research Center for Atom Technology in Tsukuba, Japan, saw a 10 % drop in resistance when they placed the material in a strong magnetic field, considerably more than the one seen in comparable materials.

Japanese researchers have identified an oxide material that may soon greatly improve the storage capacity of hard disks and magnetic tapes.

As such, this new synthetic route to oxide nanoparticles also shows great promise for a multitude of other catalytic, electrical, magnetic, or electrochemical processes, from novel cathodes to solution preparation of other types of ceramic materials.

Instead of fully eliminating the aberrations in the electron microscope, the researchers purposely added a type of aberration, called four-fold astigmatism, to collect atomic level magnetic signals from a lanthanum manganese arsenic oxide material.

In this case, the solid material was a copper oxide, a member of the transition - metal oxide family of materials, which have wide - ranging applications for their electronic, magnetic and catalytic properties.

Working with a material formed from a thick layer of one oxide — strontium titanate — and a thin layer of a second material — lanthanum aluminate — these researchers have found that the interface between these materials can exhibit magnetic behavior that is stable at room temperature.

Further testing of the material suggested that crosslinking, or bonding, using transition metals and rare - earth metals, caused the graphene oxide to possess new semiconducting, magnetic and optical properties.

Amid the situation, the NIMS research team discovered that the osmium oxide it synthesized in 2009 exhibits an unusual magnetic transition at about 140 °C, which is higher than room temperature, and had been taking on the challenge of pioneering non-catalytic, industrial functions of the material.

This behavior stems from an unusual feature of certain complex oxides called phase separation, in which tiny regions in the material exhibit vastly different electronic and magnetic properties.

Using a method that they published earlier this year, the team arranged metal - oxide nanosheets into a single plane within a material by using a magnetic field and then fixed them in place using a procedure called light - triggered in - situ vinyl polymerization, which essentially uses light to congeal a substance into a hydrogel.

«Instead of searching for new single - electron antiferromagnetic insulators like copper oxide to make high - temperature superconductors, maybe we should be searching for new highly magnetic, metallic materials that have properties like iron but in an orbitally selective arrangement,» Davis said.

Quanxi Jia, working in the areas of superconductivity, magnetic materials and thin - films, has conducted pioneering research in complex oxide thin film growth and is a recognized leader in the field of electronic device fabrication.

Using the Center for Nanoscale Materials, a DOE Office of Science user facility at Argonne, they built a constricted wire out of a three - layered structure in which a tiny layer of magnetic material is sandwiched between tantalum and tantalum - oxide layers.
