Magnetodiffractometry is a new technique n which an intense magnetic field is used to align crystalline grains1 in preparation for X-ray diffraction analysis. The field orientation greatly simplifies the resulting spectra, similar to using single crystals. This technique was instrumental in identifying the fist four-Cu layer superconductor, TlBa2Ca3Cu4Ox (T1-1234), Tc = 122 K.2 Furthermore, since well-oriented crystallites produce intense reflections, this technique allows the detection of minority phases.
