New Insights of Ferroelectric Hf0.5Zr0.5O2 Thin Films Properties Under Cryogenic Temperatures in Integrated Ferroelectric Capacitors

open access: yesAdvanced Physics Research, EarlyView.
Ferroelectric HZO capacitors are investigated from room temperature down to 40 K using reversal polarization and synchrotron GIWAXS. Polar phases stabilize at low temperatures, while domain depinning enhances reversal polarization at higher temperatures.

Element Specific Room Temperature Non‐Collinear Magnetism in the M‐Type Hexaferrite SrCo1.2Ti1.2Fe9.6O19${\rm SrCo}_{1.2}{\rm Ti}_{1.2}{\rm Fe}_{9.6}{\rm O}_{19}$

open access: yesAdvanced Physics Research, EarlyView.
Non‐collinear magnetism is of high interest in the field of magnetoelectrics supplying a convenient mechanism to break inversion symmetry and thereby allowing for a spontaneous electrical polarization. Such “multiferroics of spin origin” are inherently suitable for electric field control of magnetism, offering a route toward low power ICT applications.
