The present invention discloses a process and apparatus for forming textures in materials. It uses so called "normal aligners" having an anisotropy in the paramagnetic susceptibility within a magnetic field having compositions REBa2Cu3Ox or Bi(Tl)2Sr2Ca1-yREyCu2Ox, where RE=Eu, Er, Tm, and Yb. One version of the process for preparing bulk and elongated objects comprises two steps. In the first step the material is uniaxially aligned. In the second step uniaxially aligned material is heated to a temperature approaching its melting point while a magnetic field of at least 104 Oe, with a direction perpendicular to the axis of uniaxial alignment is simultaneously applied. The process results in biaxially, highly textured bulk and elongated materials.
