Sentences with phrase «earth permanent magnets»

Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy's Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare - earth permanent magnets.

Although samarium cobalt magnets (Sm2Co17 magnets), a type of rare earth permanent magnets, were developed in the early 1960's the underlying domain wall pinning mechanism has remained unknown.

The research cluster includes the Departments of Materials and Earth Sciences, Chemistry and Mechanical Engineering and aims to optimise the use of rare earth permanent magnets.

Not exact matches

The stronger the magnets are, the more powerful the generator — and rare earth elements such as neodymium form the basis for the most powerful permanent magnets around.

This chain acts as a permanent dipole magnet and is able to passively reorient the whole bacteria along the Earth's magnetic field lines.

The new alloy — a potential replacement for high - performance permanent magnets found in automobile engines and wind turbines — eliminates the use of one of the scarcest and costliest rare earth elements, dysprosium, and instead uses cerium, the most abundant rare earth.

Previous attempts to use cerium in rare - earth magnets failed because it reduces the Curie temperature — the temperature above which an alloy loses its permanent magnet properties.

A higher saturation magnetization obtained by increased iron content is essential for yielding larger energy products in these rare - earth Sm2Co17 - type pinning controlled permanent magnets.

The results published in Nature Communications were obtained under the framework of the LOEWE research cluster RESPONSE (Resource - Efficient Permanent Magnets by Optimised Use of Rare Earths) that is coordinated by Prof. Dr. Oliver Gutfleisch.

Strongly Exchange Coupled Core Shell Nanoparticles with High Magnetic Anisotropy: A Strategy Toward Rare - Earth - Free Permanent Magnets

These properties induce a huge improvement of the capability of storing the energy of the material, a result which suggests that the combination of highly anisotropic AFM FiM materials can be an effective strategy towards the realization of novel Rare Earth - free permanent magnets.

In particular, the application of Co-ferrite in the realization of permanent magnet has attracted a renewed interest as an alternative to rare - earth base materials in low energy applications.

The engine is paired with two Honda - developed electric motors — a propulsion motor and a generator / starter motor — that are the first drive motors in the world to use permanent magnets containing no heavy rare - earth metals.

The Honda - developed electric motors that are the first permanent magnet drive motors in the world to use magnets containing no heavy rare - earth metals.

Mountain Pass's mine contains a rare - earth ore that yields neodymium, the pixie dust of green tech — necessary for the lightweight permanent magnets that make Prius motors zoom and for the generators that give wind turbines their electrical buzz.
