Dilute ferromagnetic oxides having Curie temperatures far in excess of 300 K and exceptionally
large ordered moments per transition-metal cation challenge our understanding of …

It is generally accepted that magnetic order in an insulator requires the cation to have partially
filled shells of d or f electrons. Here we show that thin films of hafnium dioxide (HfO 2 ), an …

Room-temperature ferromagnetism is observed in (110) oriented ZnO films made from
targets containing 5 at.% of Sc, Ti, V, Fe, Co, or Ni, but not Cr, Mn, or Cu ions. There are large …

Thin films grown by pulsed-laser deposition from targets of Sn 0.95 Fe 0.05 O 2 are transparent
ferromagnets with Curie temperature and spontaneous magnetization of 610 K and 2.2 A …

Thin films of HfO 2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia,
or silicon substrates show ferromagnetic magnetization curves with little hysteresis and …

Thin films of Sn O 2 prepared by pulsed-laser deposition on R-cut sapphire substrates exhibit
ferromagnetic properties at room temperature when they are doped with Cr, Mn, Fe, Co, or …

CrAssphages are an extensive and ubiquitous family of tailed bacteriophages, predicted to
infect bacteria of the order Bacteroidales. Despite being found in ~50% of individuals and …

Room temperature ferromagnetism is found in ( Sn 1−x M x ) O 2 (M= Mn , Fe, Co, x=0.05)
ceramics where x-ray diffraction confirms the formation of a rutile-structure phase. Room …

Understanding the role of organic matter in increasing phosphorus (P) bioavailability may
lead to the development of cropping systems that can increase the efficiency of soil P use and …

There are recent reports of weak ferromagnetism in graphite 1 , 2 and synthetic carbon
materials 3 such as rhombohedral C 60 (ref. 4 ), as well as a theoretical prediction of a …
