Low voltage control of ferromagnetism in a semiconductor p-n junction
M. H. S. Owen, J. Wunderlich, V. Novak +8
The concept of low-voltage depletion and accumulation of electron charge in semiconductors, utilized in field-effect transistors (FETs), is one of the cornerstones of current infor…
Curie point singularity in the temperature derivative of resistivity in (Ga,Mn)As
V. Novak, K. Olejnik, J. Wunderlich +8
We observe a singularity in the temperature derivative of resistivity at the Curie point of high-quality (Ga,Mn)As ferromagnetic semiconductors with 's ranging from ap…
Lithographically and electrically controlled strain effects on anisotropic magnetoresistance in (Ga,Mn)As
E. De Ranieri, A. W. Rushforth, K. Vyborny +8
It has been demonstrated that magnetocrystalline anisotropies in (Ga,Mn)As are sensitive to lattice strains as small as 10^-4 and that strain can be controlled by lattice parameter…
Voltage control of magnetocrystalline anisotropy in ferromagnetic - semiconductor/piezoelectric hybrid structures
A. W. Rushforth, E. De Ranieri, J. Zemen +10
We demonstrate dynamic voltage control of the magnetic anisotropy of a (Ga,Mn)As device bonded to a piezoelectric transducer. The application of a uniaxial strain leads to a large…
