Abstract
Experimental and theoretical studies of the magnetization curves M(H) obtai ned for plates of an anisotropic hard superconductor are performed. The sam ples are YBCO single-domain textured crystals with the c axis lying in the sample plane. It is shown that, for some orientations of the magnetic field in the sample plane, the magnetization curves contain additional extrema; at the same time, the virgin magnetization curve M(H) exhibits features cha racteristic of the peak effect. This proves that the anisotropy of the curr ent-carrying ability can give rise to a new type of peak effect. (C) 2001 M AIK "Nauka/Interperiodica".
