This book focuses on recently developed crystal growth techniques
to grow large and high quality superconducting single crystals. The
techniques applied are traveling solvent floating zone (TSFZ) with
infrared image furnace, Bridgeman, solution/flux and top seeded
solution growth (TSSG) methods. The materials range from cuprates,
cobaltates to pnictides including La2CuO4-based (LCO), YBa2Cu3O7-d
(YBCO), Bi2Sr2Can 1CunO2n+4+ (n=1,2,3) (BSCCO) to NaxCoO2. The
modified Bridgman "cold finger" method is devoted to the pnictide
system with the best quality (transition width DTc~0.5 K) with
highest Tc~38.5 K of Ba0.68K0.32Fe2A2. The book presents various
iron-based superconductors with different structures, such as 1111,
122, 111, 11 and 42622,10-3-8. Detailed single crystal growth
methods (fluxes, Bridgman, floating zone), the associated
procedures and their impact to crystal size and quality are
presented. The book also describes the influence of doping on the
structure and the electric, magnetic, and superconducting
properties of these compounds in a comparative study of different
growth methods. It describes particularly under-, optimal and
over-doped with oxygen cuprates (LCO, YBCO and BSCCO) and
hole/electron/isovalently doped parent compounds AFe2As2 (A = Ba,
Sr, Ca) (122), chalcogenides AxFe2-ySe2(A = K, Rb, Cs) (122), and
Fe1-dTe1-xSex (11). A review of the current growth technologies and
future growth efforts handling volatile and poisonous components
are also presented.
