Capping-induced suppression of annealing in Ga(1-x)Mn(x)As epilayers
M. B. Stone, K. C. Ku, S. J. Potashnik +3
We have studied the effects of capping ferromagnetic Ga(1-x)Mn(x)As epilayers with a thin layer of undoped GaAs, and we find that even a few monolayers of GaAs have a significant e…
Coercive Field and Magnetization Deficit in Ga(1-x)Mn(x)As Epilayers
S. J. Potashnik, K. C. Ku, S. H. Chun +4
We have studied the field dependence of the magnetization in epilayers of the diluted magnetic semiconductor Ga(1-x)Mn(x)As for 0.0135 < x < 0.083. Measurements of the low temperat…
Saturated Ferromagnetism and Magnetization Deficit in Optimally Annealed (Ga,Mn)As Epilayers
S. J. Potashnik, K. C. Ku, R. Mahendiran +4
We examine the Mn concentration dependence of the electronic and magnetic properties of optimally annealed Ga1-xMnxAs epilayers for 1.35% < x < 8.3%. The Curie temperature (Tc), co…
Field Dependent Specific-Heat of Rare Earth Manganites
M. Roy, J. F. Mitchell, S. J. Potashnik +1
The low temperature specific heat C(H) of several rare-earth manganites (La_(0.7)Sr_(0.3)MnO_(3), Nd_(0.5)Sr_(0.5)MnO_(3), Pr_(0.5)Sr_(0.5)MnO_(3), La_(0.67)Ca_(0.33)MnO$_(3), La_(…
