MnAu$_{2}$ is one of the oldest known spin spiral materials. A common model of the spiral state of MnAu$_{2}$ is the one-dimensional Heisenberg model, where the magnetic frustration between first and second neighboring Mn planes stabilizes the spiral state. Neutron, inductance, and magneti...
A track-guided flexible closure of the sort commonly referred to as a roll-down shutter has a plurality of longitudinally interconnected elongated slats extending between two parallel tracks. The closure may be connected to the tracks by metal retaining members slidable within the associated track. ...
