We have developed a high temperature superconductor (HTS) micro SQUID magnetometer for molecular-based magnets. By employing the dipole approximation, we verified the flux value of 40Φ0 from the saturation magnetic moment of the ferrimagnetic microcrystal of [Mn2(H2O)2(CH3COO)][W(CN)8] · 2H2O (15 × 15 × 13 μm). Considering the relative arrangement of the sample and the SQUID loop, including the influence of the film and grease, the calculated the flux values were Φ = 71Φ0 and 31Φ0 at distances of 20 and 30 μm between the sample bottom face and the SQUID plane, respectively. Thus, the experimentally obtained flux value is reasonable.
Graphical abstractThe magnetic hysteresis curve of the ferrimagnetic microcrystal of [Mn2(H2O)2(CH3COO)][W(CN)8]·2H2O (15 × 15 × 13 μm) was obtained by the high temperature superconductor (HTS) micro SQUID magnetometer. The dipole approximation, considering the relative arrangement of the sample and the SQUID loop, reasonably explained the flux of 40 Φ0 from the saturation magnetic moment.Figure optionsDownload full-size imageDownload as PowerPoint slide
