Abstract

Spintronics has emerged as a field of vast applicability, and layered magnetic materials have served as a ground for advancement in this direction. Here, we report the synthesis and detailed magnetic and specific heat studies on NdSbSe, (a ZrSiS-based structure) magnetic topological material. The temperature-dependent magnetization shows the presence of competing magnetic interactions ($T_N<T<150$ K) in addition to a long-range antiferromagnetic (AFM) ordering below 4.2~K. In the AFM state, the isothermal magnetization confirms spin reorientation to the critical magnetic field of 40 kOe. Frequency-dependent ac-susceptibility measurements have probed the nonequilibrium dynamics of frustrated magnetic moments (near 150 K). The $\lambda$-like peak at 3.8~K observed in the specific heat shifts to a lower temperature with applied magnetic fields and validates the AFM order. In addition, the specific heat does not exhibit any sign corresponding to the short-range magnetic order near 150 K (spin-glass-like memory effect). In addition, the derived parameters from specific heat suggest the presence of a strong electronic correlation in NdSbSe, resulting in a Kondo-like signature in temperature-dependent resistivity data.
