Effect of annealing on carrier density and Curie temperature in epitaxial (Ga,Mn)As thin films
B. Sorensen, J. Sadowski, R. Mathieu +2
We report a clear correspondence between changes in the Curie temperature and carrier density upon annealing in epitaxially grown (Ga,Mn)As layers with thicknesses in the range bet…

Strong rejuvenation in a chiral-glass superconductor
A. Gardchareon, R. Mathieu, P. E. Jönsson +1
The glassy paramagnetic Meissner phase of a BiSrCaCuO superconductor ( = 8.18) is investigated by squid magnetometry, using ``dc-memory'' experiments employed ea…

Magnetic Properties of Short Period InGaMnAs/InGaAs Superlattices
J. Sadowski, R. Mathieu, P. Svedlindh +4
We have observed a paramagnetic-to-ferromagnetic phase transition in short period InGaMnAs/InGaAs superlattices. The thicknesses of magnetic InGaMnAs layers in the structures studi…
