Magnetic and magnetoelastic phenomena in rare earth dysprosium/lutetium superlattices and thin films
… focuses on a new epitaxial system, dysprosium/lutetium, and demonstrates that, in this case, the ferromagnetic transition temperature of Dy is enhanced above the bulk value by nearly 100%. In addition, microscopic domains of magnetoelastic distortion appear at T$\sb{\rm c}$, reducing the local …

Direct Observation of Nodal Quasiparticles in the Non-Magnetic Superconductors Yttrium(lutetium)nickel-Boron-Carbon Field-Angle Dependent Heat Capacity
The gap function in unconventional superconductors may vanish at points or lines in momentum space, permitting electronic excitations, termed nodal quasiparticles, to exist at temperatures well below the superconducting transition. In the vortex phase, the presence of nodal quasiparticles should be …

Group 3 and Group 13 Metal Hydride Compounds
… 1H NMR spectroscopy. A heterobimetallic lutetium–tungsten polyhydride cluster compound was prepared by reaction of bis cyclopentadienyl tungsten dihydride with a phenolato ligand stabilized lutetium dialkyl complex. Cluster formation proceeded via C–H bond activation of the Cp ligands …

Exohedral Functionalization and Applications of the Trimetallic Nitride Endohedral Metallofullerenes
… attributed to the large atomic number (Z) of the lutetium atoms. Mixed-metal species that contains gadolinium and lutetium or holmium and lutetium could be employed as multifunctional contrasting agents for X-ray, MRI and radiopharmaceuticals, thereby eliminating the need for three separate …

Aminopyridinato-Ligand-Stabilized Lanthanoid Complexes: Synthesis, Reactivity, Ethylene and Isoprene Polymerization
… alkyl hydrido cluster. The corresponding lutetium derivative reacts analogous to the yttrium compound. The lanthanoid alkyl hydrido clusters were characterized by X-ray structure analyses, and the presence of the hydrid ligands were clearly proved by 1H NMR spectroscopy. Dialkyl complexes, …

DEVELOPMENT OF MAGNETO-OPTIC SENSORS WITH GALLIUM IN BISMUTH DOPED RARE-EARTH IRON-GARNET THICK FILMS
… levels of gallium from z = 1.0 to 1.35. We used lutetium to control the film's in-plane magnetic properties and found that gallium doping levels above the compensation point caused a loss of anisotropy control, a canted out-of-plane magnetization in the film, and an extremely weak but linear …

X-Ray Scattering Studies of Charge and Orbital Ordering in Transition Metal Oxides
… upon cooling. We have used soft x-ray RXD on lutetium ferrate to discover an anisotropic contribution to the scattering at the charge order wavevector. This is not apparent when probing the crystal structure directly using hard x-rays. We attribute such a signal to charge-orbital order within …

Design and manufacturing of all-dielectric optical metamaterial with gradient index of refraction
… The scintillator made by ceramics like Lutetium Yttrium Orthosilicate (LYSO) possesses higher index of refraction at 1.82 than the surrounding environment, which causes extraction loss due to index mismatching and total internal reflection (TIR) from scintillator to photodetector. A …
