Abstrak/Abstract We investigate the response of electroconvective patterns to an external magnetic field H in a homeotropic nematic system where spatiotemporal chaos called soft-mode turbulence (SMT) occurs. The pattern ordering Mp , which shows pattern regularity in SMT, increases with the magnetic field H due to the suppression of the azimuthal rotational freedom. Three regions in the H-dependence of Mp are found: the zero regime, the steep increase regime and the saturated regime. In the steep increase regime, Mp shows a linear relation with H2, from which the susceptibility Xp for the pattern ordering is obtained.
