We have prepared MnSb2Se4 samples with different antisite disorders by controlling the cooling rate of the furnace. The sample S1 with the lower disorder (∼ 28 %) shows quasi-one-dimensional magnetism and exhibits type-II multiferroicity below 22.5 K [1]. The sample S2 with the higher disorder (∼ 40 %) shows a cluster-glass state supported by various DC and AC magnetization measurements. A striking observation is a colossal magnetoresistance in sample S2, which was absent in S1. Interestingly, the origin of colossal magnetoresistance is not a double exchange mechanism, as heterovalency has been ruled out by electric spin resonance (ESR) measurements. The presence of colossal magnetoresistance can be attributed to competition between various magnetic states, which adds MnSb2Se4 to the list of a handful of materials that do not belong to the manganite family, but still show negative colossal magnetoresistance.
