Topological phase transitions and Berry-phase hysteresis in exchange-coupled nanomagnets
Ahsan Ullah, Xin Li, Yunlong Jin +6
Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrm…
Inverse magnetocaloric effect in synthetic antiferromagnets
D. M. Polishchuk, M. Persson, M. M. Kulyk +5
The magnetocaloric effect in exchange-coupled synthetic-antiferromagnet multilayers is investigated experimentally and theoretically. We observe a temperature-controlled inversion…
Magneto-optical properties of topological insulator thin films with broken inversion symmetry
k. Rahim, A. Ullah, M. Tahir +1
We determine the optical response of ultrathin film topological insulators in the presence of a quantizing external magnetic field taking into account both hybridization between su…
Optical Conductivity of Topological Insulator Thin Films in a Quantizing Magnetic Field
A. Ullah, K. Sabeeh
We determine the optical response of topological insulator thin films in the presence of a quantizing, external magnetic field. We explicitly take into account hybridization betwee…
