Frustrated magnetism in antiferromagnetic nonsymmorphic square-net lattice: NdSbSe

Abstract 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 ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msub> <mml:mi>T</mml:mi> <mml:mtext>N</mml:mtext> </mml:msub> <mml:mo>&lt;</mml:mo> <mml:mi>T</mml:mi> <mml:mo>&lt;</mml:mo> <mml:mn>150</mml:mn> </mml:mrow> </mml:math> 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 λ -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.
