“…This is particularly obvious in the overdoped regime and highlights that in this compound T c is strongly suppressed. For pure Bi2201 T max c is about 13 K (Gorina et al, 1998;Vedneev et al, 1999).…”

Tunneling spectroscopy has played a central role in the experimental verification of the microscopic theory of superconductivity in classical superconductors. Initial attempts to apply the same approach to high-temperature superconductors were hampered by various problems related to the complexity of these materials. The use of scanning tunneling microscopy and spectroscopy ͑STM and STS͒ on these compounds allowed the main difficulties to be overcome. This success motivated a rapidly growing scientific community to apply this technique to high-temperature superconductors. This paper reviews the experimental highlights obtained over the last decade. The crucial efforts to gain control over the technique and to obtain reproducible results are first recalled. Then a discussion on how the STM and STS techniques have contributed to the study of some of the most unusual and remarkable properties of high-temperature superconductors is presented: the unusually large gap values and the absence of scaling with the critical temperature, the pseudogap and its relation to superconductivity, the unprecedented small size of the vortex cores and its influence on vortex matter, the unexpected electronic properties of the vortex cores, and the combination of atomic resolution and spectroscopy leading to the observation of periodic local density of states modulations in the superconducting and pseudogap states and in the vortex cores.

“…The first pure Bi-2201 samples were prepared using the flux technique, using either selfflux (CuO-based flux) [19] or KCl-flux [20]. Unfortunately, as recognized later, flux-prepared samples always suffer from several drawbacks [21]: (1) crucible material contamination due to melt corrosion at high temperatures; (2) flux impurities in as-grown samples; (3) small samples (<2 mm) in the (a,b)-plane while the typical thickness along the c-axis is less than 0.1 mm; (4) mechanical detaching of crystals from a solidified melt often causes sample damage; (5) small yield growth.…”

In this review, we summarize recent progress in crystal growth and understanding of the influence of crystal structure on superconductivity in pure and Pb-doped Bi2Sr2CuOy (Bi-2201) materials belonging to the overdoped region of high-temperature cuprate superconductors. The crystal growth of Bi-2201 superconductors faces challenges due to intricate materials chemistry and the lack of knowledge of corresponding phase diagrams. Historically, a crucible-free floating zone method emerged as the most promising growth approach for these materials, resulting in high-quality single crystals. This review outlines the described methods in the literature and the authors’ synthesis endeavors encompassing Pb-doped Bi-2201 crystals, provides a detailed structural characterization of as-grown and post-growth annealed samples, and highlights optimal growth conditions that yield large-size, single-phase, and compositionally homogeneous Bi-2201 single crystals.

“…The fact that the unit cell can be varied with the chemical composition of the initial components indicates the existence of a sizable region of homogeneity of this substance both with respect to metal components and oxygen. No further studies in this direction have been reported, although a possible strong effect of the crystal composition and corresponding point defect structure on physical properties can take place similar to those of superconducting cuprates (Liang and Lin, 2002;Gorina et al, 1998).…”

In this chapter, the various methods for crystal growth of magnetic materials are summarized and principles of choosing the appropriate growth method, which depends on phase diagram features of the alloy system, the required size, physical, and chemical perfection of single crystalline samples, are briefly discussed. The crystal growth of the following classes of materials is considered: soft magnetic pure metals and alloys, highly anisotropic compounds for high‐density magnetic recording media, rare earth–transition metal compounds for high‐performance permanent magnets, high‐magnetostrictive intermetallic compounds and ferromagnetic shape memory alloys for magnetomechanical applications, magnetocaloric materials, selected intermetallic compounds for spintronics, multiferroic materials, and some other less‐common magnetic compounds.
