Bose-Fermi mixtures of ultracold gases of dysprosium
… trapping of the most magnetic fermionic atom, dysprosium (Dy), may provide a framework to explore quantum liquid crystal (QLC) theory (Chapter 1). This thesis presents details of the Dy laser cooling and trapping apparatus including the laser systems at 421, 741, and 1064 nm, the ultra-high …

Growth and magnetoelastic behavior of b-axis-oriented dysprosium
The rare earth metals have the largest known magnetostrictions, so that their magnetic properties and structural properties are strongly coupled. This coupling is ideally suited for investigation with thin films, in which single crystal films of high quality can be prepared on substrates which …

Brillouin scattering from single-crystal dysprosium and gadolinium films
Brillouin light scattering studies have been made on the temperature dependence and dispersion of long-wavelength acoustic phonons in single-crystal Dy films and long-wavelength acoustic magnons in single-crystal Gd films. The spectra were analyzed by using elastic and magnetic continuum models for …

Optically induced ferro- and antiferromagnetic dynamics in the rare-earth metal dysprosium
… order parameter in ferro- and antiferromagnetic dysprosium (Dy), were studied by x-ray methods, which yield directly comparable quantities. The discovered fundamental differences in the temporal and spatial behavior of ferro- and antiferrmagnetic dynamics are assinged to an additional channel for …

Magnetic properties of the rare earth systems neodymium/yttrium and dysprosium/yttrium
We have studied a series of Nd/Y films and superlattices, grown by molecular beam epitaxy (MBE), using neutron, x-ray, and bulk magnetization techniques. These epitaxial Nd/Y systems are the first to be grown and studied which incorporate a light rare earth (RE) element. Using neutron diffraction, …

Dipolar Shielding and Sub-wavelength Bilayers in a Quantum Gas of Dysprosium
… Suppress Dipolar Relaxation?, by using magnetic dysprosium atoms and an optical lattice we engineered the dipolar suppression of dipolar relaxation in an ultra-cold gas prepared in an excited Zeeman level. The atoms were confined to ultra-thin layers, with their magnetic moments aligned …

Magnetic and magnetoelastic phenomena in rare earth dysprosium/lutetium superlattices and thin films
… This thesis 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 …

Paramagnetic resonance studies of trivalent dysprosium and cerium in the cubic host dicesium sodium yttrium hexachloride
We have used X-band electron paramagnetic resonance (EPR) to study octahec1rally coordinated rare earth ions in the host lattice CSNaYC16, This host is ,ideal for EPR work, because all the trivalent rare earths will substitute into the Y3+ site which has exactly octahedral symmetry, Previous EPR …

Glass microspheres for medical applications
"Radioactive dysprosium lithium borate glass microspheres have been developed as biodegradable radiation delivery vehicles for the radiation synovectomy treatment of rheumatoid arthritis. Once injected into a diseased joint, the microspheres deliver a potent dose of radiation to the diseased …

Elastic and inelastic dipolar scattering
… feature strong dipolar interactions, but we use dysprosium which is still the most magnetic atom and is easier to manipulate than molecules. However, the magnetic interaction between dysprosium atoms still needs to be stronger to be useful. Moreover, dipolar interaction can lead to detrimental …

In-Situ, in Air, High-Temperature Phase Transformations in Rare-Earth Niobates and Titanium Oxides (Dysprosium and Yttrium) Using a Thermal-Image Furnace
"The use of a co-existent ""in-situ thermometer"" was found to be a viable method to monitor the sample temperature in the image ""hot-spot"". Studies of YNbO4 and DyNbO4 revealed the existence of a new cubic phase at elevated temperatures beyond the commonly known ferroelastic …
