商品描述
The book explores the properties and behaviors of high-critical-temperature superconductors in the yttrium barium copper oxide (YBCO) system, looking specifically at Y0.5Ln0.5BaSrCu3O6+z compounds, where Ln represents rare earth elements like europium (Eu), samarium (Sm), and (neodymium) Nd. Structured into several chapters, it navigates through key aspects of superconductivity and its characterization.
Starting with an introduction to the discovery of high-critical-temperature superconductors and their far-reaching applications, it sheds light on unresolved questions in materials physics, particularly concerning the behavior of the copper(II)-oxide (CuO2) planes and the introduction of additional electronic holes. Emphasizing the pivotal role of the CuO2 planes in shaping material properties above the critical temperature, it also delves into the history of superconductivity, properties of superconducting materials, and various types of superconductors.
Phenomenological theories like the London theory, Ginzburg-Landau theory, and Abrikosov's theory of the mixed state in type II superconductors are discussed, along with conventional theories such as the BCS theory and Josephson junctions. The book provides an overview of experimental techniques used to characterize structural, magnetic, and electrical properties of superconductor compounds, including X-ray diffraction, scanning electron microscopy, and magnetometry.
Focusing on the structural, magnetic, and electrical properties of Y0.5Ln0.5BaSrCu3O6+z compounds, along with the effects of substitutions and thermal treatments, the book aims to achieve several objectives. These include a comparative study of superconducting and structural properties under various thermal treatments and isovalent substitutions, analysis of magnetic susceptibility and electrical resistivity as functions of temperature, investigation of the evolution of mixed-state properties with changing temperatures, and utilization of the Rietveld crystallographic refinement method to establish correlations between interatomic distances and critical temperatures.
Additionally, the book presents the synthesis of studied compounds through solid-state reactions and subsequent thermal treatments, including annealing under oxygen and argon atmospheres. The results of these treatments are discussed in relation to improvements in irreversibility lines, magnetic shielding, and grain quality.

本書探討了釔鋇銅氧化物（YBCO）系統中高臨界溫度超導體的特性和行為，特別關注Y0.5Ln0.5BaSrCu3O6+z化合物，其中Ln代表稀土元素，如歐洲（Eu）、鈰（Sm）和釹（Nd）。本書分為幾個章節，深入探討超導性及其特徵化的關鍵方面。
首先介紹高臨界溫度超導體的發現及其深遠的應用，並闡明材料物理中尚未解決的問題，特別是關於銅（II）氧化物（CuO2）平面行為及額外電子孔的引入。強調CuO2平面在臨界溫度以上塑造材料特性的關鍵角色，並深入探討超導性的歷史、超導材料的特性以及各類超導體。
本書討論了倫敦理論、金茲堡-朗道理論以及阿布里科索夫的II型超導體混合態理論等現象學理論，還包括BCS理論和約瑟夫森接頭等傳統理論。書中概述了用於表徵超導化合物結構、磁性和電性特性的實驗技術，包括X射線衍射、掃描電子顯微鏡和磁測量。
本書專注於Y0.5Ln0.5BaSrCu3O6+z化合物的結構、磁性和電性特性，以及替代和熱處理的影響，旨在實現幾個目標。這些目標包括在不同熱處理和等價替代下超導性和結構特性的比較研究、磁化率和電阻率隨溫度變化的分析、隨著溫度變化混合態特性的演變調查，以及利用Rietveld晶體學精修方法建立原子間距與臨界溫度之間的關聯。
此外，本書還介紹了通過固態反應和隨後的熱處理合成所研究的化合物，包括在氧氣和氬氣氣氛下的退火。這些處理的結果與不可逆線、磁屏蔽和晶粒質量的改善相關聯。
