摘要： Multiferroic articles including highly resistive, strongly ferromagnetic strained thin films of BiFe0.5Mn0.5O3 (“BFMO”) on (001) strontium titanate and Nb-doped strontium titanate substrates were prepared. The films were tetragonal with high epitaxial quality and phase purity. The magnetic moment and coercivity values at room temperature were 90 emu/cc (H=3 kOe) and 274 Oe, respectively. The magnetic transition temperature was strongly enhanced up to approximately 600 K, which is approximately 500 K higher than for pure bulk BiMnO3.

摘要： A two-dimensional vertical heteroepitaxial strain controlled composite is grown. The strain-controlling phase can be benign in all other respects so that the functional properties of the parent phase are unchanged, improved/enhanced, and/or manipulated. The new composite is advantageous because there is no need for expensive specialized crystals and because there are no thickness limitations.

摘要： An superconductive article and method of forming such an article is disclosed, the article including a substrate and a layer of a rare earth barium cuprate film upon the substrate, the rare earth barium cuprate film including two or more rare earth metals capable of yielding a superconductive composition where ion size variance between the two or more rare earth metals is characterized as greater than zero and less than about 10×10−4, and the rare earth barium cuprate film including two or more rare earth metals is further characterized as having an enhanced critical current density in comparison to a standard YBa2Cu3Oy composition under identical testing conditions.
