文摘

•: {Sm, Tb, Er}₃Co₂Ge₃ and Ho₃Ni₂Ge₃ show field sensitive antiferromagnetic ordering.
•: ΔS_m indicates a field-induced ferromagnetic ordering in {Sm, Tb, Er}₃Co₂Ge₃.
•: Ho₃Ni₂Ge₃ has a maximal ΔS_m of −10.9 J/kg K at 11 K for a field change of 50 kOe.
•: Below T_N=33 K Tb₃Ni₂Ge₃ shows an ac-AF ordering of C2′/c magnetic space group.
•: Below T_m^ND=15 K, it has additional sine-AF magnetic component with K₁=[0, 0, ±1/3].
