We show that a polar, pseudo-Jahn-Teller instability exists for the underbonded rare-earth A-site cations in the quadruple perovskite Dy_1-δMn_7+δO_12, which leads to the spontaneous formation of a dipolar glass. This observation alone expands the applicability of pseudo-Jahn-Teller physics in perovskite-derived materials, for which it is t…[Read more]

We compare inter-region patterns. Median temperature over the peripheral regions decreased from baseline after both challenges (maximum decrease °C at 60 s after exercise; and °C at 180 s of cold-water immersion; ). Median temperature over the central regions showed no significant changes. Our results show that the non-contact measurement of p…[Read more]
