Rare earth (RE – Ce, Gd) modified Nd1−xRExFeAsO0.7F0.3 superconductor with enhanced magneto-transport properties

Electronic, magnetic and transport properties of rare-earth monopnictides.

The electronic structures and magnetic properties of many rare-earth monopnictides are reviewed in this article. Possible candidate materials for spintronics devices from the rare-earth monopnictide family, i.e. high polarization (nominally half-metallic) ferromagnets and antiferromagnets, are identified. We attempt to provide a unified picture of the electronic properties of these strongly cor...

Superconducting and magneto-transport properties of BiS2 based superconductor PrO1-xFxBiS2 (x=0 to 0.9)

Effect of rare-earth (Er and Gd) substitution on the magnetic and multiferroic properties of DyFe0.5Cr0.5O3.

We report the results of our investigations on the influence of partial substitution of Er and Gd for Dy on the magnetic and magnetoelectric properties of DyFe0.5Cr0.5O3, which is known to be a multiferroic system. Magnetic susceptibility and heat capacity data, apart from confirming the occurrence of magnetic transitions at ~121 and 13 K in DyFe0.5Cr0.5O3, bring out that the lower transition t...

Superconductor Magneto-optics and Theory

Some remarks are made on how to determine by magneto-optical imaging the electric currents flowing in a superconductor. The inversion problem is discussed how to compute these currents from the magnetic field measured in a planar magneto-optical indicator film positioned close to the conductor. Next, some geometries are listed for which the currents and magnetic fields can be computed from firs...

Novel Rare-Earth-Containing Lead-Free Solders with Enhanced Ductility

Several lead-free material systems are available as replacements for traditional lead-based solders in microelectronic packaging, including near-eutectic combinations of tin-rich alloys. Although these materials have superior mechanical properties as compared to the Pb-Sn system, much work remains in developing these materials for electronic packaging. Small additions of rare-earth elements hav...
