Abstract Thermogenic brown and beige adipose tissues are important in maintaining metabolic health because of their distinct ability to catabolize stored fat and circulating glucose in futile cycles1,2. Macrophages, present in brown adipose tissue, have been reported to both positively and negatively regulate thermogenic adipocyte function through mechanisms that are incompletely understood3,4,5,6,7,8,9,10,11,12,13,14.

Abstract Intertwined superconducting and magnetic orders may give rise to exotic quantum phases1–7, including field-induced and re-entrant superconductivity8–10. However, such magnetism-enhanced superconductivity has remained elusive in superconductors with higher transition temperatures1–3. While infinite-layer nickelates represent a new class of unconventional superconductors11–20, the impact of rare-earth magnetism on superconducting properties remains largely unexplored.

Abstract Rare-earth infinite-layer nickelates are emerging unconventional superconductors, with materials synthesis largely limited to early lanthanide compounds. Here, we report phase-pure samarium-based nickelate thin films on (LaAlO3)0.3(Sr2TaAlO6)0.7 (001) substrates, including the first demonstration of Sm1-xSrxNiO2.
