Approximate eigenvalue determination of geometrically frustrated magnetic molecules
Geometrically frustrated magnetic molecules have attracted a lot of interest in the field of molecular magnetism as well as frustrated Heisenberg antiferromagnets. In this article we demonstrate how an approximate diagonalization scheme can be used in order to obtain thermodynamic and spectroscopi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Geometrically frustrated magnetic molecules have attracted a lot of interest in the field of molecular magnetism
as well as frustrated Heisenberg antiferromagnets. In this article we demonstrate how an approximate
diagonalization scheme can be used in order to obtain thermodynamic and spectroscopic information about
frustrated magnetic molecules. To this end we theoretically investigate an antiferromagnetically coupled spin
system with cuboctahedral structure modeled by an isotropic Heisenberg Hamiltonian.
Геометрично фрустрованi магнiтнi молекули привертають багато уваги як у дiлянцi молекулярного магнетизму, так i в дiлянцi фрустрованих антиферомагнетикiв Гайзенберга. У цiй статтi ми демонструємо, як наближена дiагоналiзацiйна схема може бути використана для отримання термодинамiчної i спектроскопiчної iнформацiї про фрустрованi магнiтнi молекули. М и теоретично дослiджуємо антиферомагнiтно взаємодiючу спiнову систему з кубоктаедричною структурою, модельовану iзотропним гамiльтонiаном Гайзенберга.
