Magnetic properties of DyAl0.926Cr0.074O3 and DyAlO3 were studied. We found that both compounds are antiferromagnetic with a low Néel transition temperature. At higher temperatures the magnetic characteristics show a Curie-Weiss dependence. The Néel temperature disappears when a field of about 2 T is applied, the system changes from an antiferromagnetic to a weak ferromagnetic behavior due to a metamagnetic transition. Furthermore, AC magnetic measurements in the Cr doped compound, at different frequencies, show a spin glass-like behavior. These transitions were studied and corroborated by specific heat measurements. We found the presence of metamagnetism and spin glass in the compound doped with chromium, determining that the small addition of chromium atoms modifies the magnetic properties of the compound DyAlO3, resulting in new features such as the spin glass-like behavior.
