Abstract
The scaling model of spin-glass phenomena is extended to consider both longitudinal and transverse order parameters and . The lowest-order coupling in the free energy goes as . The field () dependence of the reduced temperature for transverse freezing is found to be where is the conventional nonlinear susceptibility field exponent (). While the transverse correlation length diverges at , the longitudinal correlation length remains finite.
