Abstract
The Heisenberg spin glass is considered in the presence of two anisotropy f ields, namely, the uniaxial and cubic ones. The Gabay-Toulouse line, which signals the onset of transverse spin-glass ordering with respect to an exte rnal magnetic field, exhibits novel behavior due to the presence of the ani sotropy fields; in particular, reentrance effects may occur. Possible relat ions with experimental observations are discussed. (C) 2001 Elsevier Scienc e B.V. All rights reserved.
