Finite Size Effects on Phase Transitions using Spin Glasses

他们将完成铜锰中有限尺寸标度行为和自旋冻结温度Tg随样品厚度L减小而降低的研究，这些行为取决于不同的锰浓度、不同的中间层材料和不同的样品制备条件。他们将开始研究还原L如何影响铜锰在Tg下的不可逆性和驰豫现象等动力学性质，并开始研究铜锰以外的自旋玻璃中的3D到2D交叉。他们还将与L.P.Levy合作测量交流磁化率。

They will complete investigations of how finite size scaling bahavior and the reduction in spin-freezing temperature Tg with decreasing sample thickness L in copper manganese depend upon different manganese concentrations, different interlayer materials, and different sample preparation conditions. They will begin studies of how reducing L affects dynamical properties such as irreversibility and relaxation phenomena in copper manganese below Tg and begin studies of the 3D to 2D crossover in spin-glasses other than copper manganese. They will also measure ac susceptibility in collaboration with L.P. Levy.
