Magnetic Excitations in Magnetic Molecule {Mo214V30}

DOI

We propose to conduct inelastic neutron scattering (INS) measurements on deuterated polycrystalline samples of the magnetic molecule {Mo214V30}, to determine the low-lying magnetic excitations and their dependence on temperature and applied magnetic field using the OSIRIS. This molecule can be pictured as a paramagnetic nanosphere}, housing 30 VIV magnetic ions (spins s = ½) that occupy the sites of an icosidodecahedron of icosahedral symmetry, in contact with a diamagnetic nanoring, {Mo142}. Magnetic susceptibility measurements suggest the paramagnetic behavior originates from strong AFM nearest-neighbor V ions exchange, J ( J ~ 235) with a much weaker next-nearest interactions. Tthe absence of detailed magnetic spectra has slowed progress in developing a comprehensive theoretical model. As explained beow, OSIRIS is ideal for getting the desired magentic spectra for {V30}.
