TL;DR: In this article, the magnetic properties of DyAl0.926Cr0.074O3 and DyAlO3 were studied and it was shown that both the compounds are antiferromagnetic with a low Neel transition temperature.
Abstract: Magnetic properties of DyAl0.926Cr0.074O3 and DyAlO3 were studied. We found that both the compounds are antiferromagnetic with a low Neel transition temperature. At higher temperatures the magnetic characteristics show a Curie–Weiss dependence. Neel 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.

TL;DR: In this paper, the magnetic susceptibility and isothermal magnetization were studied on Ce x - 5 La x Ni 2 Si 3 (x = 0, 0.5, 1, 2, 3 and 4.5).
Abstract: The magnetic susceptibility and isothermal magnetization are studied on Ce x - 5 La x Ni 2 Si 3 ( x = 0 , 0.5, 1, 2, 3 and 4.5). The temperature of antiferromagnetic ordering due to the twelve magnetic Ce ions in two hexagons decreases with increasing x and is suppressed above x = 2 . The paramagnetism which arises from 2 20 of the spins lying inside the hexagonal is observed below T N in x ⩽ 1 . The signature of spin fluctuation is also observed in magnetization curves. The spin fluctuation is suppressed as the magnetic field exceeds the metamagnetic transition field.
