We have recently demonstrated that ordinary multiwalled carbon nanotubes (CNTs) develop photomagnetic and photoconductive characteristics after being modified with Ru[(bpy).sub.2] [(phen-N[H.sub.2]).sup.2+] (phen-NH2 = 5-amino-1,10-phenanthroline) through diazotization/denitrogenation processes .
We conclude that Ru[(bpy).sub.2] [(phendione).sup.2+] and APBA are redox-controllable building blocks that are useful for preparing photomagnetic carbon surfaces.
Spinel ferrites have attracted more and more attention due to their various technological applications in some fields, such as microwave absorption, high-speed digital tape, ferrofluid, magnetic recording, and photomagnetic
In contrast to typical photomagnetic properties such as light-induced excited spin state trapping (LIESST) effect, this behavior could be observed even at around room temperature.
This indicates that the FeCo complex shows appreciable crystal-water-dependent magnetic and photomagnetic properties.
