Temperature evolution of the magnetic structure of V1/3NbS2 was investigated using neutron diffraction techniques, revealing two propagation vectors and specific magnetic couplings. Magnetic susceptibility and heat capacity measurements provided insights into the antiferromagnetic transition temperature and magnetic moment saturation behavior of V1/3NbS2 under different magnetic fields.
We investigate the temperature evolution of the magnetic structure of V1/3NbS2 using neutron diffraction techniques. We find that V1/3NbS2 has two propagation vectors: k(0) = (0, 0, 0) and k(1) = (0, 0, 1/3). The k(0) vector can be associated with an antiferromagnetic ordering of in-plane moments with a refined value of 0.90(5)mu(B), and k(1) can be associated with moments along the c axis in an up-down-down configuration with refined values of 1.21(12)mu(B) and 0.61(6)mu(B). Both k(0) and k(1) magnetic components couple with an out-of-plane ferromagnetic moment consistent with magnetization data. Furthermore, single-crystal neutron diffraction shows evidence of diffuse magnetic scattering between the (010) and (01 +/- 1/3) Bragg peaks. We also characterize the field and temperature evolution of the magnetic structure in V1/3NbS2 by magnetic susceptibility and heat capacity measurements. The dc susceptibility measurements give an antiferromagnetic transition temperature of T-N = 50 K, and the field scans reveal that the moment does not saturate at magnetic fields up to 100 kOe.
