  • Diluted magnetic semiconductors are promising spintronic materials, however the simultaneous doping of charge and magnetic moment has prevented synthesis of bulk samples. This work reports the synthesis of a bulk magnetic semiconductor (Ba1−xKx)(Zn1−yMny)2As2with Curie temperatures up to 180 K.

  • Ferromagnetic systems produced by the transition metal doping of semiconductors may be used as components of spintronic devices. Here, a new ferromagnet, Li1+y(Zn1-xMnx)As, is prepared in bulk quantities and shown to have a critical temperature approaching 50 K.

  • The strong dependence of the magnetic properties on the growth conditions in (Ga, Mn)As has created the view that ferromagnetism is associated with an intrinsic inhomogeneity. Muon-spin-relaxation experiments now show that strong and homogeneous ferromagnetism is instead present in both insulating and metallic films.

  • In most unconventional superconductors, the superconducting phase is adjacent to a phase with some type of magnetic order. However, this is not a universal feature. For example, no magnetic order has so far been observed in Sr2RuO4. Now, low-energy muon relaxation experiments show the presence of a static magnetic order for this material, suggesting that this feature may in fact be universal.
