摘要：
Neutron diffraction measurements of single-crystal RbMnBr3 have been performed under magnetic fields applied parallel to the a*-axis of the prototype lattice, where the structural phase transitions are not taken into account. The critical line of a field-induced phase transition, at which the modulation wave number of the spin structure changes, has been obtained in the magnetic phase diagram for 4.2 < T < 11 K and 0 < H < 5.0 T, in addition to the in-c-plane spin-flop phase transition.
