Vacancy-induced spin-glass behavior of Prussian blue analogue FeII1.1CrIIx[CrIII (CN)6]0.6−x·nH2O nanowires
چکیده انگلیسی
Prussian blue analogue FeII1.1CrIIx[CrIII(CN)6]0.6−x·nH2O nanowires were synthesized by electrodeposition. The magnetic properties investigation indicates that the nanowires exhibit cluster spin-glass behavior, which undergoes a magnetic transition to a frozen state below about 62 K. Spin disorder arising from reduced coordination and broken exchange bonds between spin centers due to the structural defects may be the reason that causes the spin-glass freezing behavior. The negative magnetization observed at temperature lower than the compensation temperature (Tcomp∼43 K) at a field of 10 Oe may be due to the different temperature dependences of the ferromagnetic site Fe-Cr and antiferromagnetic site Cr-Cr.
