Über dieses Buch

This book provides an insight into spin-triplet superconductivity, which rapidly becomes better understood in recent years, from the perspective of a microscopic measurement technique called nuclear magnetic resonance (NMR). The compound UTe2, the target material of this book, was confirmed to show superconductivity in 2018, and its peculiarity is very similar to that of other uranium-based ferromagnetic superconductors, ensuring spin triplet superconductivity. This book begins with the fundamentals of superconductivity and subsequently overviews research in spin-triplet superconductivity. The similarity between the high-field superconducting phase in UTe2 and the superconducting phase under pressure is particularly interesting among the various superconducting phenomena observed so far. This book provides a concise introduction to superconductivity, so that the book is also intended for wide readership including the beginners interested in the phenomenon of superconductivity and undergraduate and graduate students. It also cover the NMR measurement from the basic derivation, which is accessible for beginners. The target material UTe2 is skillfully described, including a selection of related works to this book.

Chapter 1. Introduction
Abstract
In this chapter, I briefly introduce the series of U-based superconductors and spin-triplet superconductivity. The target material of this thesis is UTe\(_{2}\). I also introduce the basic experimental and theoretical reports for UTe\(_{2}\).

Chapter 2. : Paradise for Condensed-Matter Scientists
Abstract
This chapter reviews \({\text {UTe}}_{2}\), the material of interest in this study. Much more research has been published than is covered in this chapter, and many new results are still being published during the writing of this book. Note that this section only highlights the important topics related to this study.

Chapter 3. Nuclear Magnetic Resonance
Abstract
In this chapter, I briefly introduce the fundamental principle of nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) for solid-state physics. NMR is the main measurement technique for this study.

Chapter 4. Experimental
Abstract
In this chapter, I briefly describe our research mythology. These are sample details, transition temperatures, field-angle alignment of samples by NMR, the effect of temperature increase due to NMR pulses, pressure application, and pressure calibration methods.

Chapter 5. Results
Abstract
In this chapter, we summarize the NMR results that have been performed and discuss the superconducting states that are likely to be realized in UTe\(_{2}\). The superconducting state at ambient pressure and low magnetic field, the superconducting state at ambient pressure and high magnetic field, the normal state at high pressure, and the superconducting state at high pressure are reviewed in their respective sections.

Chapter 6. Summary and Future Work
Abstract
From the \( ^{125}{\text {Te}}\)-NMR measurements (Chap. 5), we have investigated the magnetic field and pressure dependence of normal state and superconducting state properties of \({\text {UTe}}_{2}\).
