Abstract

High-field magnetizations of R₂CuO₄ (R-Nd, Pr and Gd) single crystals are investigated up to 36 T at low temperatures. Nd₂CuO₄ shows two anomalous phase transitions at 2.2 and 4.2 T along the [100] direction. The keyword to solve these transitions is the staggered field due to the Cu spin. Pr₂CuO₄ shows weak linear magnetization reflecting the singlet ground state of the Pr ion. Gd₂CuO₄ shows an anomalous but systematic multistep magnetization with a magnitude of each step of about 10^-3μ_B per Gd ion in the c-plane beside the typical antiferromagnetic magnetization with small anisotropy. The origin is not clear.
