Magneto- and barocaloric properties of the ferro-antiferromagnetic sawtooth chain — •Nico Reichert1, Henrik Schlüter1, Tjark Heitmann2, Johannes Richter3, Roman Rausch4, and Jürgen Schnack1 — 1Fakultät für Physik, Universität Bielefeld — 2Fachbereich Mathematik/Informatik/Physik, Universität Osnabrück — 3Institut für Physik, Otto-von-Guericke-Universität Magdeburg; Max-Planck-Institut für Physik komplexer Systeme, Dresden — 4Institut für Mathematische Physik, Technische Universität Braunschweig
Materials that are susceptible to pressure and external magnetic fields allow the combined use of both for caloric processes. Here we report investigations of the ferromagnetic-antiferromagnetic sawtooth chain that due to its critical behavior not only allows for both barocaloric as well as magnetocaloric processes but also features very large cooling rates in the vicinity of the quantum critical point [1].
