摘要: Abstract Temperature dependent neutron elastic scattering and resistivity measurements have been made on a polycrystalline sample of Zn 0.005 Fe 2.995 O 4 , which displayed well-separated, bifurcated, heat-capacity anomaly. The lower-temperature anomaly (near 110 K) was found to be associated with lattice distortion, but no change in intensity observed at the higher-temperature 119 K). electrical this also exhibited an abrupt only downward shift lower-temperature, λ-type as result very low impurity is, however, confirmed by results demonstrates extreme sensitivity structural transition impurities.
