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这项由盖恩斯维尔佛罗里达大学的Mark Meisel和科西塞萨法里克大学的Alexander Feher合作的美国-斯洛伐克研究项目，将以研究新型低维无机磁体的热力学和磁性为特色。研究人员打算在他们最初的理论和实验证据的基础上，指出在高度各向异性的线性链反铁磁材料中存在一类新的磁激发。计划进行中子散射实验，以证实这些发现，并合成和表征新型低维磁体的粉末和单晶样品。这些结果有望有助于我们理解几个低维磁性系统的性质，特别是突出在奇异超导体(例如重费密子超导体和高T_c铜酸盐超导体)中观察到的配对机制。这个凝聚态物理项目通过使美国和中欧的顶尖专家能够将互补的人才结合在一起，并在彼此感兴趣和有能力的领域汇集研究资源，从而实现了促进科学知识的计划目标。?？
