The concepts relevant to frustrated antiferromagnets are briefly reviewed. Antiferromagnets are classified according to their symmetry groups, with non-trivial point groups leading to the possibility of multiple-Q antiferromagnetism. The role of residual degeneracy is highlighted and the manner in which this degeneracy is lifted is discussed. The physical phenomena in competition within frustrated magnets, and the states that they prefer, yield ongoing theoretical research, and the way neutron scattering can be used, in conjunction with the application of pressure and magnetic fields, to determine which of the possible magnetic structures is stabilised is under experimental scrutiny. Multiple-Q antiferromagnetism finds varied and often exotic spin states with similar energies, and as such is the setting in which phase transitions between different magnetic states can be studied.

A Current

The emergence of mesoscopic structures and the role of slow dynamics in thin magnetic films is an area of considerable interest. The role played by defect mediated dynamic processes is a current area of experimental and theoretical research that is essential to the understanding of the properties of these films. This research is driven by both the potential applications of thin magnetic films, and the fundamental questions and new physics that they point to. This brief review provides an overview of some recent experimental work on both epitaxial magnetic films and on meta-material magnetic films. An overview of some corresponding results from theory and simulation studies is also given. The article concludes with a summary and some forward-looking speculations and questions regarding these systems.

Abstract Flexible work practices (FWPs) give employees some control over when and where they work. Using boundary theory and role balance theory, this study proposes and tests a mediation model focusing on how the relationships between FWPs usage and employee outcomes (i.e., wellbeing and turnover intention) are mediated by work−life balance (WLB). It also tests the moderating role of employee age on the relationship between WLB and employee outcomes using socioemotional selectivity theory. The model was tested using survey data from 293 employees of an Australian for-profit organization. The findings indicate that FWPs usage is positively associated with WLB, WLB is positively associated with wellbeing and negatively with turnover intentions, and WLB partially mediates the relationships between FWPs usage and employee outcomes. The results provide partial support that employee age moderates the relationship between WLB and turnover intentions. Theoretical, research and practical contributions are discussed.
