Crystal Chemistry and Design Principles of Altermagnets.

Altermagnetism was very recently identified as a new type of magnetic phase beyond the conventional dichotomy of ferromagnetism (FM) and antiferromagnetism (AFM). Its globally compensated magnetization and directional spin polarization promise new properties such as spin-polarized conductivity, spin-transfer torque, anomalous Hall effect, tunneling, and giant magnetoresistance that are highly useful for the next-generation memory devices, magnetic detectors, and energy conversion. Though this area has been historically led by the thin-film community, the identification of altermagnetism ultimately relies on precise magnetic structure determination, which can be most efficiently done in bulk materials.

Enhancing childhood immunization coverage in Mozambique and Malawi: Study protocol of a mixed methods evaluation of the 'Let's talk about vaccines' multisite community-based participatory project.

Background: Full coverage of childhood vaccines is a persistent challenge in low- and middle-income countries, suggesting the presence of specific contextual barriers. The emergence of the COVID-19 pandemic further worsened the situation. The complementary use of community-based participatory research (CBPR) and human-centered design (HCD) approaches has the potential to effectively create tailored interventions for improving public health outcomes.
