Аннотация
Resonance measurements of the Nd2CuO4 single crystals at T = 1.8 K have revealed orientational phase transitions of the first order for H|| [100] and second order for H|| [110], thus pointing towards the existence of a noncollinear magnetic structure of the neodymium spin subsystem in this compound.
