Abstract

Magnetic interactions in a new geometrically frustrated system (Co_1-xFe_x)₂(OH)₃Cl are investigated using magnetic susceptibility and μSR study. While Co₂(OH)₃Cl is ferromagnetic and Fe₂(OH)₃Cl antiferromagnetic, the partially substituted series (Co_1-xFe_x)₂(OH)₃Cl show spin-glass behaviours, wherein ferromagnetic interactions prevail for low Fe concentration and antiferromagnetic ones prevail for high Fe concentration. In special, analysis of the AC magnetic susceptibility and ZF-μ⁺SR for the x=0.5 sample suggest that CoFe(OH)₃Cl has both features of chemically disordered random spin glass and geometrically frustrated spin glass. It is also the first spin-glass system for the newly found geometric frustration series M₂(OH)₃X.
