Thermoelectric transport in rare-earth compounds
… on the thermoelectric transport properties of rare-earth compounds containing Ce, Eu, and Yb. These systems have been investigated either to study fundamental problems or to evaluate their potential for thermoelectric applications.

Magnetism in crystalline rare-earth compounds
… largely due to the complex behaviour of rare-earth ions. The technique of choice is diffraction; shown to pro- vide the most lucid of results in this field of research. Neutron powder diffraction, a well established tool for determining magnetic structures, has been employed in order to …

Magnetic properties of R2PdSi3 (R = heavy rare earth) compounds
The R2PdSi3 (R = heavy rare earth) have been synthesized first in 1990 in the search for materials with unusual electronic properties. The availability of single crystals was the starting point for several investigations of the magneto-crystalline anisotropy, also in applied magnetic fields. The …

Charge Density Waves and Superconductivity in Rare Earth Compounds from First Principles
… I use first-principles simulations to study rare-earth tritellurides (RTe3) and doped rare-earth trihydrides (RH3), which host superconducting states when their charge-density-waves/structural transitions are suppressed. I develop useful computational tools for this purpose and find that the …

EXPLORATION OF NEW MULTIFUNCTIONAL MAGNETIC MATERIALS BASED ON A VARIETY OF HEUSLER ALLOYS AND RARE-EARTH COMPOUNDS
… = In, and Ga) Heusler alloys and La-Fe-Si based rare earth compounds have been synthesized and investigated by x-ray diffraction, magnetization, strain, and electrical resistivity measurements. The phase transitions, magnetic, magnetocaloric, magnetotransport and magnetoelastic properties …

Development of an Electrochemical Method to Investigate the Thermodynamic Behavior of Lanthanum and Sulfur in Liquid Steel
Since rare earth elements (REE) have great potential to improve mechanical properties of steel by refining grains and controlling the distribution and the shape of inclusions, REE may be widely used in steel industry. Currently, the method for REE separation is solvent extraction. Since this method …

Vanadium interaction with FCC catalysts
… contaminatioil on both commercial and model rare earth ion-exchanged zeolite-Y catalysts. Vanadium contamination was achieved using a standard (Mitchell) method and catalysts were subject to treatment conditions similar to those found in the regenerator part of a fluidised catalytic cracking …

A complex of interactions in rare-earth based quantum honeycomb magnets
… investigates the magnetic interactions in rare-earth honeycomb materials as potential candidates for realizing QSLs, with a focus on the exchange mechanisms governing their magnetic properties. Through a combination of magnetization, heat capacity, and inelastic neutron scattering …

Thermal Transport in Strongly Correlated Rare-Earth Intermetallic Compounds
In dieser Arbeit wurden mit Hilfe von Transportmessungen – vor allem mit thermischem Transport bei sehr tiefen Temperaturen – intermetallische Seltenerdverbindungen untersucht. Diese Materialien sind oft durch starke elektronische Korrelationen gekennzeichnet, die zu neuartigen Eigenschaften …

Up-conversion In Rare-earth Doped Micro-particles Applied To New Emissive 2d Dislays
Up-conversion (UC) in rare-earth co-doped fluorides to convert diode laser light in the near infrared to red, green and blue visible light is applied to make possible high performance emissive displays. The infrared-to-visible UC in the materials we study is a sequential form of non-linear two …
