dc.description.abstractSurface-induced disordering occurs when the order parameter for the surface layer of a magnet decays continuously to the critical temperature while the bulk exhibits a first-order transition. Due to the second-order transition in the surface, critical exponents may be defined for the power laws describing the behavior of several surface properties, e.g. the critical exponent 1 for the the surface order parameter, 1. This thesis studies the surface-induced disordering that occurs in the (111) surface of facecentered cubic AB binary alloys where the lattice transitions from an ordered L10 type structure to a disordered fcc lattice. 1 was previously estimated to be 0.64(2). This thesis increases the precision of this estimate by finding 1 = 0.624(3). Additionally, several susceptibility and specific heat critical exponents were determined.
