In this paper, we argue that available materials are not optimized for MHz power conversion applications—even those that are marketed as such—and that further development of magnetic materials is needed. In particular, we review how magnetic components are used in power converters and demonstrate ...
Hexagonal ferrites, also known as hexaferrites, are a very interesting class of materials with peculiar magnetic and electrical properties. Recently, several applications, both commercial and technological, have been developed by employing such materials, such as in magnetic recording and separation, stor...

In general, however, the magnetization dynamics of TbPc2 is severely altered in amorphous materials, where the packing of the molecules characterizing the crystalline phase is lost25,26. The origin of the phenomenon remains unclear, although it should be considered that small distortion of the two...

(II) hydroxyl halide minerals have been central to the experimental exploration into the physics of theS=12kagomé antiferromagnet in recent years10,11,12. To date, the most widely studied example of this class of materials is the Zn-paratacamite series, ZnxCu4−x(OH)6Cl2, of which the...
- 《Journal of Magnetism & Magnetic Materials》 被引量: 38发表: 2007年 Phase coexistence in the charge ordering transition in CaMn7O12 The structural phase transition in CaMn7O12 has been investigated by using high-resolution synchrotron and neutron powder diffraction. Both measurements sh... ...
Contrast agents can be of two categories such as (i) paramagnetic materials (e.g. lanthanides like gadolinium) that decrease the longitudinal (T1) relaxation resulting in a brighter signal, and (ii) superparamagnetic iron oxide nanomaterials that affect the transversal (T2) relaxation. The paramagne...
Zeolites are porous materials with improved ion exchange capacity, mainly composed of hydrated aluminosilicate minerals (El-Nahas et al. 2020). This class of adsorbent exhibit a negatively charged framework, which stems from substituting tetra atomic silicate cation for aluminium cation within the struc...
