Description:
The elastic and magnetic characteristics of single-crystal Nd 0.9 Dy 0.1 Fe 3 (BO 3 ) 4 are studied at low temperatures in zero magnetic field and in external fields H || C 3 . The temperature dependences of the acoustic mode velocities and the magnetic susceptibility manifest a transition of the magnetic subsystem into a magnetically ordered state and two successive, spontaneous spin-reorientation phase transitions. The possibility of a spontaneous transition into an incommensurate (spiral) magnetic phase in the crystal is discussed. It is shown that an external magnetic field directed along the trigonal axis of the crystal induces a sequence of spin-reorientation phase transitions. An H-T phase diagram ( H || C 3 ) is constructed for this compound.
