Dynamic Spin Fluctuations in the Frustrated A-site Spinel CuAl2O4
Hwanbeom Cho, R. Nirmala, Jaehong Jeong +7
We performed nuclear magnetic resonance (NMR) and muon spin relaxation (μSR) experiments to identify the magnetic ground state of the frustrated quantum A-site spinel, CuAl2O4. Our…
Electronic structure investigation of GdNi using X-ray absorption, magnetic circular dichroism and hard x-ray photoemission spectroscopy
C. W. Chuang, H. J. Lin, F. M. F. de Groot +8
GdNi is a ferrimagnetic material with a Curie temperature Tc = 69 K which exhibits a large magnetocaloric effect, making it useful for magnetic refrigerator applications. We invest…
Observation of spin glass state in weakly ferromagnetic SrFeCoO double perovskite
R. Pradheesh, Harikrishnan S. Nair, C. M. N. Kumar +7
We report the observation of spin glass state in the double perovskite oxide SrFeCoO prepared through sol-gel technique. Initial structural studies using x rays reveal…
Magnetocaloric effect in R2Ti3Ge4 (R = Gd, Tb and Er) Compounds
R. Nirmala, Darshan C. Kundaliya, A. V. Morozkin +1
Heat capacity of polycrystalline R2Ti3Ge4 (R = Gd, Tb and Er) compounds (Orthorhombic, Sm5Ge4-type, Space group Pnma) has been studied in the temperature range of 1.8 K to 300 K in…
Tuning the Competing magnetic interactions in RTiGe (R = Tb, Er) Compounds and tailoring the Magnetocaloric effect
R. Nirmala, S. K. Malik
The tetragonal layered compounds TbTiGe and ErTiGe order antiferromagnetically at 276 K and 39 K, respectively. Partial substitution of Mo for Ti in these two compounds modifies th…
Large magnetoresistance in intermetallic compounds R2Mn3Si5 (R = Tb, Dy and Ho)
R. Nirmala, S. K. Malik, A. V. Morozkin +2
Magnetization (M) and magnetoresistance (MR) measurements on polycrystalline R2Mn3Si5 (R = Tb, Dy and Ho) compounds (tetragonal, space group P4/mnc) have been carried out in the te…
