Abstract (EN): This work describes an extensive study of the compound 11HFBBBM7*([1]), which presents the SmCalpha* phase in a relatively large temperature interval (approximate to 3.3 degrees C). The polarization hysteresis loops obtained at stabilized temperatures disclosed an antiferroelectric behaviour in the high temperature range of the SmCalpha* phase. Dielectric dispersion was studied as a function of the bias field.
