Dublin, Dec. 22, 2016 (GLOBE NEWSWIRE) -- Research and Markets has announced the addition of the "Permanent Rare Earth Magnets Market - Drivers, Opportunities, Trends & Forecasts: 2015-2022" report to their offering. The global permanent rare earth magnets market is expected to grow at a CAGR of 13.2% during the forecast period to reach $41.41 billion by 2022. Industrial applications segment is expected to maintain global dominance in application segments, whereas China and Japan driven Asia Pacific is expected to increase its dominance in global permanent rare earth magnets market. Currently, China is the global leader in rare earth oxide supply covering more than 90% of the global market. This has translated to Chinese dominance in rare earth magnets market. After China, Japan is the major market for rare earth magnets. Although a significant portion of products end-up being utilized in developed countries of the US and Western Europe; these products are largely sourced from developing countries in South Asian region. The increasing demand for efficient products across the industries would drive the demand for rare earth magnets with highest growth rate expectations from wind turbine market. The global supply of rare earth metals is expected to remain stable after WTO intervention and international agreements providing opportunities for sustainable market growth. The international players are also looking for other ways to reduce the dependencies, such as options of heavy rare earth free magnets, but the overall market is expected to remain stable in terms of price during the forecast period. Some of the prominent players in the global permanent rare earth magnets market are Hitachi Metals, Vacuumschmelze GmBH & Co. KG, Shin-Etsu Rare Earth Magnet and TDK.

A common problem for elliptically polarizing undula-tors (EPUs) is that the magnetic forces give a mechanical deflection in the magnet holder construction when changing the undulator phase. Gluing horizontally and vertically magnetized blocks together can increase the mechanical stability of the magnet holders. The gluing process of pairs of magnetized magnet blocks is time-consuming, expensive and difficult to carry out with high positional precision. A novel magnet production technique has been developed where un-magnetized pairs of blocks are glued together before magnetization. The large number of parts, the time for assembly, and the cost of the EPU can be reduced with the novel magnet production technique. The novel magnet production method has been used for a 2.6 m long EPU of APPLE-II type, which has been built in-house at the MAX IV Laboratory. The frame for the EPU is made of cast iron in order to get a small mechanical deformation when changing phase in the inclined mode. The paper includes detailed descriptions of the novel magnet production technique, including measurements of the magnetization, and the new EPU.

In amorphous and nanocrystalline transition metal based alloys with low magnetostriction, the soft magnetic properties are mainly determined by magneto-elastic and annealing-induced anisotropies which are uniform on a scale much larger than the exchange correlation length. Though, in the nanocrystalline case, there are situations where the random magneto-crystalline anisotropy of the grains becomes relevant. The present paper surveys the interplay between the random magneto-crystalline and the uniform field-induced anisotropy in nanocrystalline FeCuNbSiB soft magnets. Typical examples where the contribution of the random anisotropy becomes particularly visible in the magnetic domain structure will be reviewed. © 2009.


A laminate stack having individual soft magnetic sheets. The individual sheets are involutely curved in the laminate stack. Each individual sheet has a first long side, a second long side opposite the first long side, a first short side and a second short side opposite the first short side. The first long side has a recess, said recess being rectangular and equidistant from the first short side, the second short side and the second long side when the individual sheet is in its uncurved state.
