Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films
Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19
Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…

Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
