摘要:
The effects of pressure on the microstructure and magnetic properties of Co-Fe bistable Prussian blue analogues (PBA) were investigated by Mossbauer spectroscopy and magnetic measurements. Na0.54Co1.23[Fe(CN)(6)]center dot 7.6H(2)O was prepared by the co-precipitation method and pressurized at 1-40 MPa using a supercritical CO2 extraction unit. All materials are face-centered cubic with a Neel temperature of about 14 K. The results showed that two electronic configurations existed in the NaCoFe-PBA system at room temperature: Fe-LS(III)-CN-Co-HS(II) and Fe-LS(II)-CN-Co-LS(III). The pressure in...
