Investigating effective spin - ½ magnetic ground state in 3D cubic system Li3Nd3Te2O12 via inelastic neutron scattering
Abstract: Rare-earth based systems are an excellent platform for studying the exotic ground states of matter arising due to the interplay of Spin Orbit Coupling (SOC) and Crystal Field (CF) effects. Our recent studies on a cubic Li3Nd3Te2O12 (LNTO) give signatures that it may exhibit a Jeff = ground state. Reduced magnetic moment at low temperatures is a preliminary indicator for this behaviour. From the two-level Schottky fitting of heat capacity data, it is shown that the gap between the ground state doublet is increasing with increasing applied magnetic field. The value of Lande g-factor obtained from the fitting closely matches with the calculated values obtained from the Brillouin fit of the field-dependent magnetization data at 2 K. Additionally, from the two-level fitting of magnetic susceptibility, it is obtained that the energy gap between ground and first excited states is ~17 meV. To directly confirm this, we propose to perform inelastic neutron scattering (INS) on a polycrystalline sample of LNTO and its nonmagnetic analoge Li3Y3Te2O12 using the MARI spectrometer. The data will be collected from 5 K to 300 K with incident energy 100 meV to understand the CF exitations and its temperature evolution. INS data combined with thermodynamic measurements will establish the CF parameters and hence confirm the presence of Jeff = ground state, and offer key insights in to the exotic magnetism offered by Nd based quantum magnets.
