Magnonics is a research field complementary to spintronics, in which the quanta of spin waves (magnons) replace electrons as information carriers, promising lower dissipation1,2,3. The development of ultrafast, nanoscale magnonic logic circuits calls for new tools and materials to generate coherent …

In oxide heterostructures, different materials are integrated into a single artificial crystal, resulting in a breaking of inversion-symmetry across the heterointerfaces. A notable example is the interface between polar and non-polar materials, where valence discontinuities lead to otherwise…

Non-universal current flow near the metal-insulator transition in an oxide interface
Persky E, Vardi N, Monteiro AMRVL, van Thiel TC, Yoon H, Xie Y, Fauqué B, Caviglia A, Hwang HY, Behnia K, Ruhman J, Kalisky B.

Nature communications. 2021;12(1):3311

In systems near phase transitions, macroscopic properties often follow algebraic scaling laws, determined by the dimensionality and the underlying symmetries of the system. The emergence of such universal scaling implies that microscopic details are irrelevant. Here, we locally investigate the…

Ultrafast phononic switching of magnetization
Stupakiewicz A, Davies CS, Szerenos K, Afanasiev D, Rabinovich KS, Boris AV, Caviglia A, Kimel AV, Kirilyuk A.

Nature physics. 2021;17(4):489-492

Identifying efficient pathways to control and modify the order parameter of a macroscopic phase in materials is an important ongoing challenge. One way to do this is via the excitation of a high-frequency mode that couples to the order, and this is the ultimate goal of the field of ultrafast phase…
