本论文介绍了中子散射数据，有助于凝聚态物理学的四个不同领域的理解，包括iso-composite液-液相变和稀土掺杂钛酸钡玻璃的形成。将激光加热的原位气动悬浮与中子散射相结合，研究了（Y_2O_3）_x（Al_2O_3）_1-x的液-液相变以及因瓦合金中的原子有序和磁有序。在几个重要的结果，在这种情况下，从小角中子散射，是在一个范围内的温度和组成的铝酸钇的相变的情况下。由于这些是一个主要的系统，其中液-液相变已被假设，这是一个有争议的领域的重要贡献。
This thesis presents neutron scattering data that contribute to the understanding of four distinct areas of condensed matter physics, including iso-compositional liquid-liquid phase transitions and the glass formation in rare earth doped BaTi2O5. In situ aerodynamic levitation with laser heating was combined with neutron scattering in order to study both liquid-liquid phase transitions in (Y2O3) x (Al2O3) 1-x and the atomic and magnetic ordering in liquid Invar. Among several significant results, obtained in this case from small angle neutron scattering, was the absence of a phase transition across a range of temperatures and compositions in the yttria aluminates. As these are a principal system in which liquid-liquid phase transitions have been hypothesized, this is an important contribution in a contentious area.
