Reentrant spin-glasses FexMn1-xTiO3 with x = 0.60, 0.65 and 0.75, which are magnetically non-diluted short-range systems, have been studied by low-field DC-magnetization, neutron scattering and Mössbauer measurements. Their reentrant behavior is shown to appear most remarkably among the systems examined so far, which will give important information to clarify the reentrant mechanism.
