Sintering the pellets above 700 °C completely suppresses ferromagnetism to below room temperature. It is well accepted that Mn clusters would be antiferromagnetic and hence severely suppress the ...

The recent discovery of magnetic materials that are also superconductors has reconciled two physical phenomena that were previously thought to be incompatible. Putting on the pressure The startling ...

Scientists believe they’ve made a concrete example of an unusual, theoretical form of ferromagnetism first described by a researcher more than 50 years ago. Nagaoka ferromagnetism, named for the ...
