Unravelling the signatures of effective spin1/2moments in CeVO: magnetization and heat capacity study.

The realization of an effective spin () ½ state at low temperatures offers a platform to study the enthralling physics behind the disordered states in certain systems. Here, we report the signatures of magnetic ground state associated with= ½ in CeVO. Our studies confirm the absence of any ordering or freezing down to 1.8 K. In the low temperature region, the Curie-Weiss fit of the inverse DC susceptibility indicate towards the presence of antiferromagnetic correlations among the Cespins. The calculated value of effective moment (∼1.16μB) corresponds to= ½ with∼ 1.20. Further, the field dependent magnetization curve at 2 K follows a behaviour corresponding to= ½ Brillouin function with∼ 1.13. Magnetic field dependent heat capacity fits very well with two-level Schottky scheme. Our investigations suggest that CeVOcan be a promising candidate to realise= ½ properties among 3D spin systems.
