[008940 . 40]迈瑟尔，马克。迈瑟尔，盖恩斯维尔佛罗里达大学的马克。迈瑟尔和他的合作伙伴科希斯P.J.萨法里克大学的亚历山大。费赫尔共同开展了一个美国和斯洛伐克的研究项目，主要研究各种新型低维无机磁体的热力学和磁性。已知和新材料，包括各种化合物的粉末和晶体，构成模型自旋链和阶梯系统，将通过结合宏观和微观探针的混合来表征，这些探针可以跨越温度，磁场和压力的范围。主题材料包括：自旋阶梯、交替自旋链、交替交换链、单离子束缚态和低维偶极系统。结果有望提高我们对几种低维磁系统性质的基本理解，并有可能提高我们对外来超导体中配对机制的理解。这个凝聚态物理项目通过使美国和中欧的专家能够在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。

INT 0089140Meisel, MarkThis U.S.-Slovak research project between Mark Meisel at the University of Florida, Gainesville, and his partner Alexander Feher of P.J. Safarik University, Kosice, features an investigation of the thermodynamic and magnetic properties of a variety of novel low-dimensional inorganic magnets. Know and new materials, including powders and crystals of a variety of compounds constituting model spin chain and ladder systems, will be characterized by combining a blend of macroscopic and microscopic probes that span a range of temperature, magnetic field and pressure. Subject materials include: spin ladders, alternating spin chains, alternating exchange chains, single-ion bound states, and low-dimensional ising dipolar systems. Results are expected to improve our basic understanding of the properties of several low-dimensional magnetic systems and, potentially, the pairing mechanisms in exotic superconductors.This condensed matter physics project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
