Sažetak
Molecular magnets are being investigated as a part of our search for multifunctional materials as well as our need for the fundamental understanding of magnetism. Among a large number of new compounds, oxalate complexes of transition metals are interesting because of high efficiency of oxalate bridge (C2O42–) in transmission of exchange interaction between metal ions. One of the most important methods in solid state physics is electron spin resonance (ESR) which gives insight into local properties of paramagnetic centers and microscopic picture of interactions in the investigated systems. Commercial ESR spectrometers (X-band) which use microwaves of frequency ν = 9.5 GHz and magnetic field B up to 1 T, are not appropriate for investigation of the transition metal complexes with spin S > 1/2. In order to obtain the spin Hamiltonian parameters in these systems: g-tensor, D-tensor (zero-field splitting) and A-tensor (hyperfine splitting), it is necessary to have spectrometers that operate in high magnetic fields and at high frequencies (High Field-High Frequency ESR, HF-ESR).
