Distinct field-induced ferroquadrupolar states for two different magnetic-field directions in DyNiAl
Original language description
The hexagonal compound DyNiAl undergoes ferromagnetic and antiferromagnetic-type magnetic phase transitions at TC = 30 K and T1 = 15 K, respectively. To investigate the 4f-electronic state and quadrupole interactions, we carried out ultrasonic measurements versus temperature and magnetic field. The transverse elastic moduli C44 and C66 show a prominent softening originating from an interlevel ferroquadrupolar-type interaction between the ground state and excited Kramers doublets. In magnetic fields applied along the [100] and [001] axes, we observed a field-induced phase transition. Because the quadrupole interaction is enhanced in high magnetic fields according to our calculations, we suggest a magnetic-field-induced ferroquadrupolar ordering of the electric quadrupoles Oxz and Oyz for fields applied along [100] and [001], respectively, with different quadrupolar order parameters depending on the field direction.
