Critical behavior in the itinerant ferromagnet SmMn2Ge2

doi:10.1088/1674-1056/accb49

Abstract Transition metal and rare earth intermetallics have been a fertile playground for research of various quantum states. We report detailed magnetic studies on SmMn₂Ge₂, an anisotropic itinerant magnet with multiple magnetic phases. The critical behavior of the ferromagnetic phase transition is investigated by employing the modified Arrott plot with the Kouvel-Fisher method. The critical temperature TC is determined to be around 342.7 K with critical exponents of β =0.417 and γ=1.122, and the interaction function is found to be J(r)～ r^-4.68, suggesting the coexistence of long-range and short-range magnetic interactions. Our results contribute to the understanding of complex magnetism in SmMn₂Ge₂, which may provide fundamental guidance in future spintronic applications.
