The worldwide spread of COVID‐19 has resulted in an enormous threat to public health, causing global panic, especially older adults suffering severe anxiety due to their vulnerability. With a questionnaire survey on 213 Chinese older adults in April 2020, we examined the role of community resilience in protecting older adults from anxiety during the COVID‐19 pandemic, and simultaneously considered the moderating role of trust in local government. The results indicated that community resilience was negatively associated with older adults' anxiety, and this association was weakened for older adults with low trust in local government. This study has implications for intervention designs that combine resilient factors related to communities and local governments to relieve older adults' anxiety during the pandemic.

Rare-earth iron garnet films with perpendicular magnetic anisotropy (PMA) are important to develop magnon-based spintronic devices. In this study, high quality epitaxial Ho3Fe5O12 (HoIG) films with PMA are fabricated on (111) Y3(Sc2Ga3)O12 substrates by sputtering. The magnetization compensation temperature of HoIG films is determined to be 130 K, highly consistent with its bulk value. The magnetic dead layer at the interface is quantified as thin as about 0.6 nm through polarized neutron reflectivity. Furthermore, spin–orbit torque switching in HoIG/Pt films is realized with the threshold current density of 1.4 × 1011 A/m2 and assisting field as small as 10 Oe. These results provide one more alternative for spintronic materials using compensated ferrimagnetic insulators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
