Field-induced Polar Order at the Néel Temperature of Chromium in Rare-earth Orthochromites: Interplay of Rare-earth and Cr Magnetism
B. Rajeswaran, D. I. Khomskii, A. K. Zvezdin +2
We report field-induced switchable polarization (P = 0.2 ~ 0.8 microC/cm2) below the Néel temperature of chromium (TN Cr) in weakly ferromagnetic rareearth orthochromites, RCrO3 (R…
Glassy behavior in the ferromagnetic and the non-magnetic insulating states of the rare earth manganates, Ln0.7Ba0.3MnO3 (Ln = Nd or Gd)
Asish K. Kundu, P. Nordblad, C. N. R. Rao
While La0.7Ba0.3MnO3 is a ferromagnetic metal (TC = 340 K) with longrange ordering, Nd0.7Ba0.3MnO3 shows a transition around 150 K with a small increase in magnetization, but remai…
Enhancement of ferromagnetism by Co and Ni substitution in the perovskite LaBiMn2O6+d
Asish K. Kundu, V. Pralong, V. Caignaert +2
The substitution of cobalt and nickel for manganese in the perovskite manganate LaBiMn2O6+d; has been realized, leading to the perovskites LaBiMn2-x(M)xO6+d, with M = Co, Ni and x…
Non-equilibrium Magnetic Properties of Single Crystalline La0.7Ca0.3CoO3
Asish K. Kundu, P. Nordblad, C. N. R. Rao
Magnetic and electric properties of a single crystal of La0.7Ca0.3CoO3 have been experimentally studied. The system attains a ferromagnetic spontaneous moment below 170 K and exhib…
Inhomogeneous magnetic behavior of Pr0.7Ca0.3CoO3 and Nd0.7Ca0.3CoO3
Asish K. Kundu, E. V. Sampathkumaran, K. V. Gopalakrishnan +1
Unlike La0.7Ca0.3CoO2.97, Pr0.7Ca0.3CoO3 and Nd0.7Ca0.3CoO2.95 do not show distinct ferromagnetic transitions, but instead they exhibit very low magnetic moments down to 50 K. A de…
Current-induced phase control in charged-ordered Nd0.5Ca0.5MnO3 and Pr0.6Ca0.4MnO3 crystals
Sachin Parashar, L. Sudheendra, A. R. Raju +1
Single crystals of Nd0.5Ca0.5MnO3 and Pr0.6Ca0.4MnO3 show current-induced insulator-metal transitions at low temperatures. In addition, the charge-ordering transition temperature d…
