【摘要】

：

近年来，磁性纳米结构中自旋转移力矩效应(STT)引起了一些新奇的物理现象，如STT 磁矩翻转、磁矩进动以及自旋二极管效应。自旋二极管效应可以用来设计一种新型的纳米微波探测器，其显著优点是有可能克服半导体二极管(如Schottky 二极管)理论探测极限，实现微弱信号的高灵敏检测。然而，在绝大部分报道的研究中，器件需要在外加磁场下才能工作，这对实际应用是不利的。

β-PdBi2超导态的点接触谱研究

电子量子态的拓扑性质成为目前凝聚态物理的研究热点之一,其独特的物理现象和潜在的应用价值吸引了人们的广泛关注. 其中,拓扑超导体是探寻 Majorana 费米子的理想平台.最近,超导转变温度TC= 5.2 K 的 β-PdBi2 超导体的角分辨光电子谱测量表明β-PdBi2 在超导态之上具有拓扑对称性保护的表面态 1,极有可能是拓扑超导体.

CeO2掺杂对单畴SmBCO超导块材超导性能的影响

本文采用新型顶部籽晶熔渗生长法(Sm+011 TSIG)制备出了直径为20mm 掺杂1wt％CeO2和未掺杂的单畴SmBCO 超导块材.在77K 零场冷轴对称条件下测量了其与直径20mm、表面磁场0.5T 的永久磁体之间的磁悬浮力,样品的最大磁悬浮力分别为54 N 和43 N,结果表明,掺杂CeO2能够显著提高样品的超导性能,单位面积的磁悬浮力达到17.2N/cm2,说明CeO2 掺杂能够提高Sm
