Canted magnetic structure of a Honeycomb lattice NdPt6Al3 using neutron diffraction
Honeycomb lattice magnets have attracted considerable attraction due to the bond dependent exchange interactions based on the exactly solvable Kitaev Honeycomb model, resulting in a quantum spin-liquid ground state. We have investigated honeycomb lattice CePt6Al3 using neutron diffraction and muon spin rotation, which revealed a paramagnetic ground state down to 90 mK, which is surprising and opens debate whether geometrical frustration supresses the magnetic ordering to T = 0 K. To understand this unusual behaviour, we have now synthesised NdPt6Al3, which exhibits a magnetic ground state as evident from the bulk measurements. In fact, the heat capacity reveals a sharp maximum at 1.2 K, indicating a long-range magnetic ordering. Furthermore, our single crystal magnetization shows easy-plane anisotropy with a spontaneous ferromagnetic moment of 0.26 żB/Nd for a field perpendicular to the c-axis. We expect that the small FM component in the AFM ordered state is caused by canting of the Nd moments by the Dzyaloshinski-Moriya interaction as recently suggested for GdPt6Al3. We propose to investigate the canted magnetic structure of NdPt6Al3 in the presence of DM interaction using D20.
