Robust spin splitting and fermiology in a layered altermagnet
Alessandro De Vita, Chiara Bigi, Davide Romanin +42
Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…
Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…
Uncovering surface states of the Dirac semimetal BaMg2Bi2
A. De Vita, J. Bakkelund, H. ÅwiÄ tek +13
BaMg2Bi2 is a Dirac semimetal characterized by a simple Dirac cone crossing the Fermi level at the center of the Brillouin zone, protected by C3 rotational symmetry. Together with…
Irreversible multi-band effects and Lifshitz transitions at the LaAlO3/SrTiO3 interface under field effect
Ilaria Pallecchi, Nicolo' Lorenzini, Mian Akif Safeen +4
In this work, we investigate the irreversible effects of an applied electric field on the magnetotransport properties of LaAlO3/SrTiO3 conducting interfaces, with focus on their mu…
