为了弄清 LaAl_2晶体的令人感兴趣的性质——超导性和磁性共存——的起源,我们利用 DHVA效应研究了该晶体。正在测量 Fermi 面的 Gamma 心叶上的 Dingle 温度各向异性。由于存在磁交互作用,造成与可比频率混频,从而使这一分析更为复杂。Dingle 温度是用 Coleridge 等的分波解析法用R.de Groot 和 F.Mueller 计算的分波系数分析的。此外,正在利用波形分析,以测定 Fermi 面的较小叶的从属于自旋的散射程度和交换 Hamilton 函数的大小。自旋分裂零位的研究已揭示出 gamma 心叶上的可能选择对象。在纯 LaAl_2晶体中它看来大约
To understand the origin of the interesting properties of LaAl 2 crystals - superconductivity and magnetic coexistence - we investigated the crystal using the DHVA effect. Dingle temperature anisotropy is being measured on the Gamma heart leaf of the Fermi surface. This analysis is more complicated due to the magnetic interaction that results in mixing with comparable frequencies. The Dingle temperature is analyzed by the democratization method of Coleridge et al. Using the demultiplication coefficients calculated by R. de Groot and F. Mueller. In addition, waveform analysis is being used to determine the extent of spin-dependent scattering and the exchange of Hamiltonian functions for the smaller leaf of the Fermi surface. Studies of spin-splitting zero have revealed possible candidates for gamma-heart lobes. It appears to be about in pure LaAl 2 crystals
