Fractional Spin fluctuations and quantum liquid signature in Gd2ZnIrO6
Birender Singh, Deepu Kumar, Vivek Kumar +5
Hitherto, the discrete identification of quantum spin liquid phase, holy grail of condensed matter physics, remains a challenging task experimentally. However, the precursor of qua…
Coupling of lattice, spin and intra-configurational excitations of Eu3+ in Eu2ZnIrO6
Birender Singh, M. Vogl, S. Wurmehl +3
In Eu2ZnIrO6, effectively two atoms are active i.e. Ir is magnetically active, which results in complex magnetic ordering within the Ir sublattice at low temperature. On the other…
Kramer doublets, phonons, crystal-field excitations and their coupling in Nd2ZnIrO6
Birender Singh, M. Vogl, S. Wurmehl +3
We report comprehensive Raman-scattering measurements on a single crystal of double-perovskite Nd2ZnIrO6 in temperature range of 4-330 K, and spanning a broad spectral range from 2…
Kitaev Magnetism and Fractionalized Excitations in Double Perovskite Sm2ZnIrO6
Birender Singh, M. Vogl, S. Wurmehl +3
The quest for Kitaev spin liquids in particular three dimensional solids is long sought goal in condensed matter physics, as these states may give rise to exotic new types of quasi…
Correlated Paramagnetism and Interplay of Magnetic and Phononic Degrees of Freedom in 3d-5d Coupled La2CuIrO6
Birender Singh, Deepu Kumar, Kaustuv Manna +6
Conventional Paramagnetism - a state with finite magnetic moment per ion sans long range magnetic ordering, but with lowering temperature the moment on each ion picks up a particul…
High Field Ultrasound Measurements in UPt3 and the Single Energy Scale Model of Metamagnetism
B. S. Shivaram, V. W. Ulrich, Pradeep Kumar +1
We report longitudinal ultrasound velocity measurements for magnetic fields up to 33 T applied parallel to the a-axis of the heavy electron compound UPt. A characteristic dip…
