Experimental magnetization-versus-field curves from Ref. 21 (a) and Ref. 22 (b). The asymmetry of the field shift and a “small pedestal” for are clearly seen.
Diagram of the model proposed for a bilayer ferromagnetic in contact with an uncompensated boundary of an antiferromagnet.
Phase diagram of a bilayer model of a ferromagnet in the variables . The regions of stability of the collinear phases ↑↑, ↓↓, and ↑↓ and a noncollinear phase (NC) in the absence (a) and presence (b, c) of anisotropy in the easy plane are shown: (b) and , (c) ( are dimensionless anisotropy constants).
Longitudinal (solid lines) and transverse (dashed lines) magnetization versus the external field for different values of the parameter : a) , b) , c) .
Field dependences of the component of the magnetization of the first (1) and second (2) ferromagnetic layers: a) , b) , c) .
Field dependences of the energy for different values of the parameter : a) , b) , c) . The solid and dashed lines correspond to stable and unstable, respectively, states.
