“…These values are much lower than the theoretical saturated values of one Ln 3+ (Gd 3+ , g J × J = 2 × 7/2 = 7 N β ; Dy 3+ , g J × J = 4/3 × 15/2 = 10 N β ), which could be attributed to significant magnetic anisotropy of the crystal field induced splitting of the m J level 42 together with Dy 3+ ions. Gd-based magnetorefrigerant materials exhibit an outstanding magnetocaloric effect due to the intrinsic characteristics of Gd 3+ ions (half-filled 4f orbital, magnetic isotropy and weak exchange interactions 43 ). Magnetization data for 1 were obtained at a field of 0.25–7 T between 2 and 10 K. −Δ S m values were calculated using the Maxwell equation: .…”

“…The value of 29.96 J kg −1 K −1 is higher than most reported dinuclear complexes of antiferromagnetic coupling except a value of 31.33 J kg −1 K −1 (Table 2). [ 48–63 ] Therefore, it is a kind of magnetic refrigerating material with good performance.…”

Molecular magnetic refrigerating material is a kind of green and environmentally friendly materials, which achieve the purpose of cooling by its magnetocaloric effect. Magnetic density is crucial to the magnetocaloric effect of the complexes, and it is usually described by the parameters of Mw/NGd or metal/ligand mass ratio, which represents the content of Gd (III) in the complexes. In order to establish the functional relation between these parameters and magnetocaloric effect, doping is a credible method without changing the coordination environment of the system, which is realized by the process of increasing Gd (III) gradually in the diamagnetic complex. Hence, a diamagnetic dinuclear Y2, four doped samples Gd0.24Y1.76, Gd0.51Y1.49, Gd1.04Y0.96, and Gd1.46Y0.54, and a pure dinuclear Gd2 were synthesized and characterized. Through the measurement of magnetic properties and data fitting, the functional relations were obtained between these parameters and −ΔSm in this dinuclear system. It is the first time that the relationships are set up via experimental design, and it will contribute to observation and comprehension of how magnetic density affects the magnetocaloric effect. In addition, the −ΔSm of dinuclear Gd2 is 29.96 J kg−1 K−1, which is higher than most of the reported dinuclear Gd (III)‐based complexes.
