Enhancement of ferromagnetism by p-wave Cooper pairing in superconducting ferromagnets

In superconducting ferromagnets for which the Curie temperature $T_{m}$ exceeds the superconducting transition temperature $T_{c}$, it was suggested that ferromagnetic spin fluctuations could lead to superconductivity with p-wave spin triplet Cooper pairing. Using the Stoner model of itinerant ferromagnetism, we study the feedback effect of the p-wave superconductivity on the ferromagnetism. Below $T_{c}$, the ferromagnetism is enhanced by the p-wave superconductivity. At zero temperature, the critical Stoner value for itinerant ferromagnetism is reduced by the strength of the p-wave pairing potential, and the magnetization increases correspondingly. More important, our results suggest that once Stoner ferromagnetism is established, $T_m$ is unlikely to ever be below $T_c$. For strong and weak ferromagnetism, three and two peaks in the temperature dependence of the specific heat are respectively predicted, the upper peak in the latter case corresponding to a first-order transition.Comment: 6 pages, 6 figures, submitted to Phys.

Foreign correspondents: a case study of China in the digital and globalization age

While Western foreign correspondence is retreating, Chinese central media and correspondents, resourced by the government’s financial backing for media’s role in public diplomacy, are taking the opportunities to expand overseas bureaus, hire experienced local employees, enhance the quantity and quality of international news reporting, use digital technologies in newsgathering and dissemination, and receive Western-style trainings. Against this backdrop, this paper studies the identities, media cultures, and journalistic practices of Chinese foreign correspondents, as well as the international news output, and media–audience and media–foreign policy relationships. In doing so, we propose a new six-level theoretical model: (1) journalists’ identities; (2) cultures; (3) practices; (4) news output; (5) news dissemination, reception, and audiences’ interactions; and (6) the impacts of international news coverage. Based on semi-structured interviews with Chinese resident journalists over eight years, we argue that the media–audience and media–foreign policy relationships in China have become more interactive, dynamic, and complex
