Effect of Ga irradiation on magnetic and magnetotransport properties in (Ga,Mn)As epilayers
H. Kato, K. Hamaya, Y. Kitamoto +2
We report on the magnetic and magnetotransport properties of ferromagnetic semiconductor (Ga,Mn)As modified by Ga ion irradiation using focused ion beam. A marked reduction i…

Mixed magnetic phases in (Ga,Mn)As epilayers
K. Hamaya, T. Taniyama, Y. Kitamoto +1
Two different ferromagnetic-paramagnetic transitions are detected in (Ga,Mn)As/GaAs(001) epilayers from ac susceptibility measurements: transition at a higher temperature results f…
