Abstract
We investigated in this paper a new mixture +3/+2 B cations delafossites by the doping at Cr
3+
sites in CuCrO
2
by nonmagnetic cation Ti
2+
. Ceramics of CuCr
1−
x
Ti
x
O
2
(0≤
x
≤0.1) were prepared via solid state synthesis techniques in a controlled atmosphere of O
2
. The compound crystallized into the 3R delafossite phase with hexagonal structure. The slightly different size in B cations induced a slightly variation in unit cell parameters. We modulate the spin chirality by the effect of spin dilution for Ti
2+
on the structural and magnetic properties of delafossite CuCrO

having a
S
=3/2 antiferromagnetic triangular lattice (ATL).
