Seminarium "Modeling of Complex Systems"

Ca3Ru2O7 is an antiferromagnetic (AFM) polar metal considered a fascinating material due to its wide range of remarkable electronic phenomena, including colossal magnetoresistance, spin waves, and multiple phase transitions. Exploring these properties under external manipulation, such as electrical current, pressure, or strain, opens new pathways for understanding its electronic behavior and controlling its quantum states. In this study, we employ ab initio methods to investigate the stability of several AFM configurations of Ca3Ru2O7 under lattice deformation (pressure and strain). We identify potential altermagnetic (AM) states, a recently discovered elemental magnetic phase, and show that these states can be stabilized under strain. We discussthe underlying mechanisms responsible for the stability of the AM phase and propose a novel route for tuning quantum states through AFM to AM transitions in Ca3Ru2O7 under lattice deformation. Tuning magnetic phases from AFM-metal (ground state) to AM-insulator under strain.
