Abstract :
We have successfully prepared EuO films on Si(100) wafers via pulsed laser deposition (PLD). It is well recognized that EuO grows with texture growth along (100) but the addition of 4% Gd changes the lattice constant and the texture growth to (111) as well as having a profound influence on the magnetic properties. The differences in the effects between Gd doping and oxygen vacancies, both expected to be n-type (donor state) dopants in EuO, are discussed.
