“…Among various antiferromagnets, face-centered-cubic (fcc)-like Mn thin films are considered to be highly attractive systems because they can be fabricated with current epitaxial growth techniques [19][20][21][22][23][24][25][26]. Although theoretical studies have suggested that the behavior of bulk fcc-like Mn could be a function of the lattice parameters, on the basis of the rich magnetic phase diagram of bulk fcc-like Mn [27,28], for Mn thin films directly grown on FM films with stable in-plane magnetization (or vice versa), experiments involving spinpolarized scanning tunneling microscopy (SP-STM) and x-ray magnetic circular dichroism (XMCD)-based photoemission microscopy (PEEM) have supported in-plane layered AFM structures [10,23,24,29].…”

We report an experimental investigation of the magnetoelastic effects of ultrathin antiferromagnets, performed by comparing the characteristic behavior of the induced spin-reorientation transition (SRT) of Co films in two types of epitaxially grown bilayers: face-centered-cubic (fcc)-like Mn/Co (fcc-Mn: a = 3.75Å, c = 3.76Å) and face-centered-tetragonal (fct)-Mn (a = 3.61Å, c = 3.78Å). Magnetic hysteresis loops and magnetic domain images indicate that both fcc-Mn and fct-Mn films can produce a 110 to 100 SRT in adjacent Co films when the thickness of the Mn layer is greater than a temperature-dependent critical value. Detailed analysis of the critical thickness of Mn films and the evolution of the Co domain structure upon SRT indicate that the fct-Mn film had a higher antiferromagnetic ordering temperature and stronger lateral Mn-Mn exchange coupling compared with the fcc-Mn film. The enhanced long-range antiferromagnetic ordering emerging concurrently with the in-plane lattice variation of the fcc-like Mn film in Mn/Co bilayers clearly showed the magnetoelastic effect of ultrathin antiferromagnets.
