INT 9722935 Meisel This U.S.-Slovak research project between Mark Meisel of the University of Florida, Gainesville, and Alexander Feher of the Safarik University, Kosice, will feature the investigation of the thermodynamic and magnetic properties of novel low dimensional inorganic magnets. The researchers intend to build upon their initial theoretical and experimental evidence that points to a new class of magnetic excitations in a highly anisotropic linear chain antiferromagnetic material. Neutron scattering experiments are planned to confirm these findings as well as synthesis and characterization of powder and single crystals samples of the new low dimensional magnets. Results are expected to contribute to our understanding of the properties of several low dimensional magnetic systems, specifically highlighting the pairing mechanisms observed in exotic superconductors (e.g., heavy-fermion and high-Tc cuprate superconductors.) This project in condensed matter physics fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Central Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ??

INT 9722935 Meisel 这是佛罗里达大学盖恩斯维尔分校的 Mark Meisel 和科希策 Safarik 大学的 Alexander Feher 之间的美国-斯洛伐克研究项目，重点研究新型低维无机磁体的热力学和磁性。 研究人员打算以他们最初的理论和实验证据为基础，指出高度各向异性线性链反铁磁材料中的一类新的磁激发。 计划进行中子散射实验来证实这些发现以及新型低维磁体的粉末和单晶样品的合成和表征。 预计结果将有助于我们理解几种低维磁系统的特性，特别强调在奇异超导体（例如重费米子和高温铜酸盐超导体）中观察到的配对机制。该凝聚态物理项目完成了该计划目标是通过使美国和中欧的领先专家在共同感兴趣和能力强的领域结合互补人才并汇集研究资源来推进科学知识。 ??
