“…T c values agree with previously reported data on similar superlattices. 15,16 Additionally, interdiffusion could also be invoked to account for the depression of the critical tmperature when the YBCO thickness is reduced. It is well known that that a 45% ͑atomic͒ Pr interdiffusion into the first YBCO layer, would result in a T c of 30 K for the resulting alloy.…”

Interaction of ambient nitrogen gas and laser ablated carbon plume: Formation of CN

“…For ablation in reactive gases like oxygen and nitrogen simple oxide and nitride molecules are also formed in the expanding ablation plume resulting in oxide and nitride films on the substrate [3][4][5][6][7]. Among the several characteristics that distinguish PLD from other film growth techniques is congruent deposition, and hence it has been used to grow superconducting superlattices and superconducting device structures [8]. Recently, combinatorial methods, an approach in which a large number of materials are synthesized, processed and screened Nuclear Instruments and Methods in Physics Research B 192 (2002) [301][302][303][304][305][306][307][308][309][310] www.elsevier.com/locate/nimb for specific properties have been applied to the discovery and optimization of several functional materials [9,10].…”

Effect of Interlayer Coupling on Néel Temperature in Antiferromagnets

“…According to them, the Niel temperature in copper-based antiferromagnets falls logarithmically with decreasing interlayer coupling. Li et al [9] have shown that the coupling between layers is essential in case of 1-2-3 to achieve a superconducting transition temperature of 90 K. They have also studied the effect of layer thickness on the interlayer coupling in copper oxide-based superlattices. Most of these results are obtained in a 2D or quasi-2D Heisenberg model.…”
