Abstract

The relationship between charge and spin degrees of freedom in a geometrically frustrated system, [Formula presented] spinel, is investigated. Upon Cr doping, the charge-ordered phase of [Formula presented] is rapidly suppressed and a charge-disordered phase grows up instead. It is found that the magnetic ground state is a spin-glass state dominated by geometrical frustration for both phases, but larger spin entropy remains down to low temperatures in the charge-ordered phase, possibly owing to its two-dimensional character.
