Query: Compositional Studies of Metals with Complex Order by means of the
  Optical Floating-Zone Technique   The availability of large high-quality single crystals is an important
prerequisite for many studies in solid-state research. The optical
floating-zone technique is an elegant method to grow such crystals, offering
potential to prepare samples that may be hardly accessible with other
techniques. As elaborated in this report, examples include single crystals with
intentional compositional gradients, deliberate off-stoichiometry, or complex
metallurgy. For the cubic chiral magnets Mn$_{1-x}$Fe$_{x}$Si and
Fe$_{1-x}$Co$_{x}$Si, we prepared single crystals in which the composition was
varied during growth from $x = 0 - 0.15$ and from $x = 0.1 - 0.3$,
respectively. Such samples allowed us to efficiently study the evolution of the
magnetic properties as a function of composition, as demonstrated by means of
neutron scattering. For the archetypical chiral magnet MnSi and the itinerant
antiferromagnet CrB$_{2}$, we grew single crystals with varying initial
manganese (0.99 to 1.04) and boron (1.95 to 2.1) content. Measurements of the
low-temperature properties addressed the correlation between magnetic
transition temperature and sample quality. Furthermore, we prepared single
crystals of the diborides ErB$_{2}$, MnB$_{2}$, and VB$_{2}$. In addition to
high vapor pressures, these materials suffer from peritectic formation,
potential decomposition, and high melting temperature, respectively.
