Abstract
Thin films of disordered hexaborides Ca B6 and Sr B6 deposited by pulsed-laser deposition on MgO (100) or Al2 O3 (001) substrates are ferromagnetic. A typical room-temperature moment per unit area of substrate is 350 μB nm-2, with the largest values being found for Ca B6 on Al2 O3. Lattice defects are the likely origin of the exotic, high-temperature magnetism. The moment, which is present in films as thin as 12 nm, appears to reside in an interface layer whose polarization is approximately 0.4 Tesla. © 2004 American Institute of Physics.
