Absence of dipolar ordering in Co doped CuO
N Vijay Prakash Chaudhary, J. Krishna Murthy, A. Venimadhav
Polycrystalline CuO samples with Co doping were prepared by solid state method with flowing oxygen condition and examined their structural and multiferroic properties. Structural s…
Giant magnetocaloric effect in Gd2NiMnO6 and Gd2CoMnO6 ferromagnetic insulators
J. Krishna Murthy, K. Devi Chandrasekhar, Sudipta Mahana +2
We have investigated magnetocaloric effect in double perovskite Gd2NiMnO6 (GNMO) and Gd2CoMnO6 (GCMO) samples by magnetic and heat capacity measurements. Ferromagnetic ordering is…
Antisite disorder driven spontaneous exchange bias effect in La2-xSrxCoMnO6 (0<x<1)
J. Krishna Murthy, K. D. Chandrasekhar, H. C. Wu +3
Doping at the rare-earth site by divalent alkaline-earth ions in perovskite lattice has witnessed a variety of magnetic and electronic orders with spatially correlated charge, spin…
Investigation of intrinsic magnetodielectric effect in La2CoMnO6: Role of magnetic disorder
J. Krishna Murthya, K. Devi Chandrasekhar S. Murugavel, A. Venimadhav
We present a large magnetodielectric (MD) effect of 65 % at 100 kHz with 5 T field in B-site ordered La2CoMnO6 (LCMO) polycrystalline sample. Frequency and temperature dependent im…
Multicaloric effect in multiferroic Y2CoMnO6
J. Krishna Murthy, A. Venimadhav
We have investigated multiple caloric effects in multiferroic Y2CoMnO6. Polycrystalline sample prepared by solid state method has shown a ferromagnetic Curie temperature 75 K with…
Metamagnetic behavior and effect of field cooling on sharp magnetization jumps in multiferroic Y2CoMnO6
J. Krishna Murthy, K. Devi Chandrasekhar, H. C. Wu +3
We present sharp magnetization jumps and field induced irreversibility in magnetization in multiferroic Y2CoMnO6. Appearance of magnetic relaxation and field sweep rate dependence…
