High-pressure studies of DyB$$_2$$C$$_2$$

We performed single-crystal neutron diffraction experiments and electrical resistivity measurements under high pressure on DyB$$_2$$C$$_2$$ showing both of the antiferroquadrupolar (AFQ) and antiferromagnetic (AFM) orders. The N$'e$el temperature $$T_N$$ increases gradually with increasing pressure and saturates above 5.2 GPa while the AFQ transition temperature $$T_Q$$ decreases almost monotonically up to 3.13 GPa and seems to merge with $$T_N$$ at around 6-7 GPa. These results indicate that the application of pressure suppresses the AFQ ordering in DyB$$_2$$C$$_2$$ and simultaneously enhances the AFM interaction between 4$$f$$ spins. The suppression of the AFQ ordering can be interpreted as being due to the restriction of the local strain associated with the AFQ transition by applying pressure.
