Permittivity exhibits a strong peak near the ferroelectric phase transition at 215 K. This is mainly due to softening of the lowest frequency polar phonon revealed in THz and infrared spectra. The magnetic measurements performed at various frequencies in field-cooled and field-heating regime after cooling in zero magnetic fields excluded spin-glass behavior and proved an antiferromagnetic order below 1.9 K in Eu0.5Ba0.5TiO3.
