Continuous spin reorientation in antiferromagnetic films
J. J. Alonso, J. F. Fernandez
We study anisotropic antiferromagnetic one-layer films with dipolar and nearest-neighbor exchange interactions. We obtain a unified phase diagram as a function of effective uniaxia…

Van der Waals loops and the melting transition in two dimensions
J. J. Alonso, J. F. Fernandez
Evidence for the existence of van der Waals loops in pressure p versus volume v plots has for some time supported the belief that melting in two dimensions is a first order phase t…
